Since this is the era of surveying that the project I'm working on involves, and I was looking at some Mt. Shasta observations yesterday, I thought I'd post a story written by one of our chief of parties.  I've got a paper copy of this some where - thanks go to the 
College of the Siskiyous for their 
Mt. Shasta Collection for putting it online for others.   I've stolen their web page as is here.

  In what follows I state facts for the information of those interested, rather 
  than draw on my imagination to please the reader. Every one who ascends a high 
  mountain has his own experience, and there are sensations peculiar to each individual. 
  For my own part, although accustomed to mountain climbing, I have found nothing 
  more difficult than to describe accurately what I have seen, and it is even 
  more difficult to describe the sensations of one who remains for a long time 
  at a great elevation.
During the summer of 1878 Mr. Carlisle P. Patterson, Superintendent United States 
  Coast and Geodetic Survey, authorized Professor George Davison, Assistant, to 
  place a theodolite and heliotrope on Mount Shasta, in connection with the work 
  then going on under the Professor's direction. Professor Davidson assigned the 
  duty to me, and in executing it I arrived at Sisson's July 18th. Sisson's, a 
  country inn and summer resort, is a place pleasant in itself, but to the dusty 
  traveler by stage or the weary tourist after an expedition in the mountains 
  or on the lakes or river in the vicinity, it is a paradise. From Sisson's to 
  the summit of Mount Shasta is about twelve miles, in a straight line, and the 
  ascent about 10,440 feet. Sisson's house is about 4,000 feet above the sea. 
  Mount Shasta is 14,440 feet high, as determined by barometer. Mr. A.F. Rodgers, 
  Assistant United States Coast and Geodetic Survey, and his party, were the first 
  from the Survey to ascend Shasta and remain over night. His first ascent was 
  
April 30th, 1875, and his second in October of the same year. He had the weather 
  no colder than I did, and all of his party seem to have suffered from the rarefied 
  atmosphere. He was up three days, and 
erected an iron signal surmounted by a parabolic reflector, which is yet standing.
On the 24th of July we left Sisson's Hotel to make the ascent. The day was a 
  delightful one, and we were all in fine spirits. The outfit which I proposed 
  taking up weighed seven hundred and fifty pounds, and had to packed from the 
  snow line to the summit on the backs of twenty stout Indians. Besides the packers 
  there was the usual number of squaws, papooses, and lean dogs - the indispensable 
  impedimenta of Indian bucks. If there is anything outside of these household 
  chattels that a buck in this neighborhood prides himself on it if his linen 
  duster and jaunty straw hat. The former, to be stylish, must reach to within 
  six inches of the ground, and for the latter a broad blue or red band is most 
  desirable. Nearly every one in the party was mounted, and it was a somewhat 
  noisy company, in which the voices of the bucks and squaws were mingled with 
  the crying of papooses and the barking of dogs, so that no one sound was clearly 
  distinguishable. Our route was over a beautiful smooth mountain trail, which 
  at first wound about in splendid forests of sugar-pine. The ascent was so gradual 
  that it would have been imperceptible to a casual observer. To the mountaineer, 
  however, no better evidence of increasing elevation was necessary than the gradual 
  change, first in size and shape, and finally in the species of the trees. By 
  the time we had ridden two hours the sugar-pine was much smaller, and interspersed 
  with red fir. At the end of three hours the sugar-pine had disappeared entirely, 
  and we had red fir only. An hour later and we passed through the most beautiful 
  forest of these trees that I have ever seen. It was entirely free from underbrush, 
  the trees were young and vigorous, and their symmetrical and beautifully tapering 
  trunks and branches, towering many feet above our heads, were decorated with 
  very delicate and pretty yellow mosses. There were tracks of deer in and across 
  the trail everywhere, and occasionally a bear's track could be seen, but our 
  noise frightened them and they hid away.
We arrived at the upper edge of the timber at 3 P.M., where above us towered 
  the beautiful snow-clad peak of Shasta. Here we were to spend the night and 
  be ready for the ascent in the morning. The squaws picketed the ponies where 
  they could obtain a scanty meal from the grass, which was just beginning to 
  spring up among the rocks. The guide sent some of the bucks to walk over the 
  snow while it was soft from the noonday sun, in order that we might save cutting 
  places in it for our feet when we began the ascent in the morning. Near our 
  camp-fire was the dry bed of a brook. By sunset it was a noisy mountain stream, 
  which gradually increased in volume until nearly sunrise, when it began to fall, 
  and by noon it was dry again. This takes place every day in summer when there 
  are no clouds, and is caused by the melting of the snow on the mountain side. 
  Before dark we had partaken of our evening meal of cold food and hot coffee. 
  Our blankets were then spread on the ground, and we were soon asleep. This was 
  a short-lived pleasure; for we were awakened in a short time by the Indians, 
  who, under their medicine-man - a shred old knave, and not to fond of work - 
  were performing such ceremonies as are customary with them before undertaking 
  any important affair. How long they continued their monotonous chanting, I do 
  not know; for I quickly fell asleep under its influence, and did not awake until 
  the first light streak was visible in the east, announcing the approach of sunrise 
  and the beginning of our day's labor.
Comparatively few Indians have ever been to the summit of Mount Shasta, and 
  these generally with white men. With them it seems to be a sacred place, and 
  its snowy mantle they regard with reverence as an emblem of purity; nor will 
  they defile it even with tobacco-juice. We partook of a hasty breakfast of hot 
  coffee and cold food, and were soon at the place where the packs had been sorted 
  out and left. They averaged from thirty-five to forty pounds each, which is 
  a fair load for one man to carry to the summit. The morning was clear. There 
  was no wind, and the atmosphere was sharp and bracing - the thermometer standing 
  at 32". The trail that the Indians had previously tramped in the snow was 
  followed step by step. But for this precaution no footing would have been secure 
  without expending much time and labor in chopping our way in the snow. The first 
  red snow was found at about ten thousand feet. The microscopic fungi which constitute 
  the coloring matter were very abundant. Where the footprints were deep enough 
  to pass through it, they presented the appearance of one's having left stains 
  of blood around the edges of his tracks. It had decidedly a fruity taste; but 
  none of us agreed as to what it was like. Sisson thought it resembled the flavor 
  of ripe pears, while to me it was water-melon A handful of it melted on a newspaper, 
  leaves, after the water has evaporated, a red, powdery substance, feeling on 
  the hands much like fine Indian meal. The upper part of the snow, for a depth 
  of two inches, was as white as usual, and of the ordinary granular form of old 
  snow, like finely ground alum salt, hard packed. Below this came the red stratum, 
  which was about three inches thick - the white again appearing under this. As 
  we ascended slowly over the snow-field, it became steeper and steeper - our 
  trail finally bearing off in the direction of an abrupt rocky hillside, leading 
  up to the backbone of one of the ridges that radiate from the summit. Should 
  one lose footing here, while the snow is frozen, there is little probability 
  of being able to stop until he had slid some three or four thousand feet. He 
  would make it very quickly, however; and I should apprehend no danger beyond 
  the loss of a little skin, which would probably be rubbed off. The worst part 
  of such a performance on my own account would have been the necessity of climbing 
  back again.
While on the snow-field some one shouted, "Look! look!" and there, 
  about a mile off, where a large rock, called "The Thumb," projects 
  from the backbone, was a cloud effect more beautiful than I ever expect to see 
  again. A small cloud seemed to have been hovering just behind the ridge from 
  us; the morning sun had warmed it up, and just as the sun was high enough to 
  welcome us with his genial warmth, the cloud came creeping over the ridge, and 
  partially enveloped "The Thumb" in a robe, the colors of which were 
  more beautiful than I can describe, and which changed incessantly, and finally, 
  in a few moments, disappeared as silently as it had some before us. The impression 
  left on my mind was that of al the colors of many rainbows passing rapidly into 
  each other in endless confusion. We were soon over the snow-field, and at the 
  foot of the rocky slope before alluded to. I did not like the looks of the immense 
  boulders that I saw piled up above us on a hillside - so steep that in ascending 
  it both hands and feet were constantly required - many of them so evenly balanced 
  that a man's weight would start them tumbling from their resting places. It 
  is this alone that constitutes the danger of an ascent of Shasta; even this 
  danger can and should be avoided by going around such places. I was behind all 
  the others, encouraging those who showed signs of exhaustion, when one of the 
  packers accidentally dislodged a boulder about six feet in diameter. We were 
  all on the lookout and endeavoring to avoid such an accident, and as soon as 
  it started several called, "Look out!" On looking up I saw it coming 
  down about fifty yards above me. I sprang aside as quickly as I could, and was 
  just in time. I felt the wind from it as it went tearing by me, and was hit 
  by some small fragments, but not at all injured. I followed it with my eyes 
  as it went plunging downward. It was at once followed by a steam of other rocks 
  that it had set in motion, and at the foot of the rocky hill the whole was launched 
  in a confused mass on the hard, frozen snow-field, where stones of all sizes 
  joined in a "go-as-you-please" rolling match, tracing curves that 
  crossed and recrossed each other in all kinds of complications. They finally 
  disappeared behind a turn, but we heard them some seconds after, when they had 
  passed the line of the snow and were crashing and grinding among the rocks in 
  the canon below. As they gradually came to rest the sound died away as in the 
  distance, leaving silence again to reign in its kingdom.
At the top of this hill we passed around the foot of "
The Thumb" and 
  found ourselves under the red bluff, a steep wall of pumice that is readily 
  distinguishable from Sisson's. We passed around this wall over a snow-drift 
  to the eastward of it. This drift seemed to have formed against a perpendicular 
  wall, but it had melted away and left a deep, narrow chasm, the bottom of which 
  was not visible. On top it was about thirty feet wide, and on the outside it 
  fell off precipitously for three or four hundred feet. This is at an elevation 
  of about thirteen thousand feet, and is where tourist generally begin to feel 
  the effects of the light atmosphere. The medicine-man gave out here, and his 
  pack was taken by one of the supernumeraries. The strongest of the men now advanced 
  but slowly and only fifty or sixty yards at a time before stopping to get wind. 
  The last of the packers had not yet passed the snow-drift when we were enveloped 
  in a very dense, cold fog, the approach of which I had not observed, being busily 
  engaged at the time in getting the packers over the drift. Frost formed rapidly 
  on our beards and clothing, and exercise was necessary for comfort. The packers 
  were scattered, the stronger ones being considerably in advance, and not being 
  able to see twenty feet in any direction, they all began calling at once. I 
  hastened to the front and stopped the calling, and detained those in advance 
  until those behind came up, when we resumed our journey again. Although there 
  only remained about thirteen hundred feet to climb, it proved by far the most 
  fatiguing part of the journey; the rarefied atmosphere making frequent halts 
  necessary. During these halts each buck who had a linen duster would straighten 
  himself up, look around in a patronizing way at his companions less fortunate 
  than himself, and with an air of comfort wonderful to behold, would button it 
  to the throat as carefully as one's overcoat is buttoned to bid defiance to 
  the cold. Two squaws, who came to pack, gave out here, but they went on without 
  their packs to the Hot Springs. I shall always remember with pleasure the gallant 
  manner in which the stronger bucks vied with each other in carrying the packs 
  of these women, and the kindly words with which they were encouraged to go on 
  to the end would be creditable to any people.
By noon the last pound of the outfit was deposited near the Shasta Hot Springs, 
  two hundred and fifteen feet below the summit, where I intended to camp. As 
  each Indian threw down his pack he swore in good plain English that he would 
  never come up again, and cursed white men in general for doing such work. I 
  noted carefully, and was surprised to see how varied their physical condition 
  was. Some were panting from their exertions, and perspiring freely; in which 
  condition they threw themselves at full length on the snow and refused to move. 
  Others who had done the same work were shivering with cold, and sought the hot 
  ground around the springs, where, stretching themselves on the warm sulphur 
  beds, they remained shivering in spite of their linen dusters until they were 
  sufficiently rested to begin the descent. A fair estimate of the condition of 
  these men may be made when it is known that there were twenty in all; that only 
  five of them had ever been to the summit' that they were now within two hundred 
  and fifteen feet of it; that the fog was clearing away beautifully - and not 
  one of them went up. When the last packer had gone, I found myself, with two 
  attendants - Richard Hubbard and Thomas Sullivan, both fine specimens of vigorous 
  manhood - ready to go to work to make ourselves as comfortable as circumstances 
  would permit. Our first care was to provide water, which was done by melting 
  snow in a large tin vessel at the Hot Springs. Then our tent was pitched in 
  as comfortable a place as we could find; and soon our little coal-oil stove 
  was in operation and we were preparing our coffee. Thomas Sullivan was then 
  taken sick. His head troubled him so that he could not work, he began to suffer 
  from cold hands and feet, and in a short time this was followed by sickness 
  at the stomach, which compelled him to give up entirely. We wrapped him in blankets, 
  and placed him in a corner of the tent on some robes to thaw out. By the time 
  we had made our tent secure and snug it was dark. The thermometer was standing 
  at 30", there was a light wind from the southward, and a clear sky, in 
  which the stars were shining with extraordinary brilliancy, We spread our bed 
  on the rocky floor of the ten, and crawled under the blankets, with Sullivan 
  between us, in order, if possible, to warm him up, He was very restless all 
  night, and was up from time to time, suffering very much from violent nausea. 
  This interfered very much with our rest, and I was glad when it was light enough 
  to get up. Sullivan's purple, haggard face and bloodshot eyes showed that he 
  had suffered considerably, and I was glad to see him leave as soon as the sun 
  was up, Being now unencumbered and in a splendid condition for work, we began 
  with a will, ad although compelled to stop frequently for want of breath, we 
  had by noon packed the instruments and observing tent to the summit, and made 
  fair progress in setting them up. By night I was ready to observe on Lola and 
  Helena, or show a heliotrope to Professor Davidson, who was at the former place.

  The summit of Mount Shasta consists of two conical peaks about two hundred yards 
  apart. The northeast one is about fifty feet the higher, and is called Shasta 
  Peak; the southwest one I called McLean's Peak, in honor of Doctor McLean of 
  Oakland, who spend two nights and a day on the summit with me. It is in the 
  valley between these peaks that the Shasta Hot Springs are situated. They are 
  dotted about over an area of about twenty yards square, and constantly send 
  up steam strongly impregnated with light sulphureted hydrogen and other gases, 
  the odor of which is offensive and very oppressive, so much so that in making 
  examinations of them it is impossible to hold one's head in the fumes near the 
  ground, and breathe. The temperature of these springs was carefully measured, 
  and found to be 184o. One can walk about easily over them, but I always considered 
  it safe to have some one near to give assistance in case of accident, and to 
  carry an alpenstock in my hand to assist myself with in case I fell through 
  the crust, which consist of loose earth and small stones cemented together with 
  sulphur, alum, and other minerals. Hubbard broke the crust over on of the springs 
  with his alpenstock, and disclosed the mouth of quite a cavern, from which the 
  steam rolled out in great volumes. Another opening sent out the steam in a small 
  jet that caused a hissing noise much like that made by the steam escaping from 
  a locomotive. I thought them all more active on some days than on others; but 
  was unable to discover any change of temperature on these occasions. Mr. Carneal, 
  of Oakland, spent two nights on the summit with me, and standing at my side 
  on the north end of Shasta Peak, he discovered another group of hot springs 
  on the north side, resembling in all respects the Shasta Hot Springs, but by 
  no means so active. I named them Carneal Hot Springs. Whether the heat form 
  these springs is volcanic or chemical I do not know, but I am inclined to think 
  it chemical.
The whole top of the mountain consists of ashes, lava, and igneous rocks. They 
  are disintegrating all the time, and a camping-place should be selected with 
  a view of being out of the way of any of the large rocks that are liable to 
  tumble at any time. Seldom a night passed that we did not hear one that had 
  lost its balance, go tearing and crashing down to the next bench. Once we left 
  our tent, not exactly panic-stricken, but at least in fair haste, when on came 
  quite near us. On McLean's Peak the pock is of a dark-brown color, is of igneous 
  origin, and broken into immense boulders, that are now so much displaced as 
  to leave room for conjecture as to whether the long, deep grooves that apparently 
  extended, at one time, for hundreds of feet, are due to glacial action or not. 
  They have been so long exposed to the weather that small striae would have had 
  time to wear out entirely. The Whitney glacier has its origin about one thousand 
  feet below the northwest from these furrows. Many of the stones have very beautiful 
  lichens on them, but on the Shasta Peak there are none. One day I found some 
  snow-birds and sparrows dead in the snow; they had probably been caught on the 
  mountain in a cold fog, and perished before they could get away. I saw chipmunks 
  one thousand feet above the timber line, and once I saw a hawk on the top of 
  McLean's Peak; but it only remained a few seconds and then flew away. There 
  were a few of the ordinary blue-flies that crawled about sluggishly inside the 
  tent during the warmer hours of the day, but they were quite torpid by three 
  o'clock. The delicate little spiders that I have seen floating about with their 
  webs on other high mountains, as though carried there by the wind, were not 
  seen here.
Most Californians are aware that from the latter part of July util the first 
  rains - which generally fall in October - the atmosphere is filled with smoke, 
  which is often so dense that one can only see a mile or two in any direction. 
  This season had just begun when I climbed Shasta, and although on many days 
  it prevented my seeing the surrounding country, it enabled me to see that it 
  seldom reached higher than twelve thousand feet. Looking to the westward, the 
  line of smoke was always as well defined as a sea horizon. It seemed always 
  to terminate on the side next me in an immense wall, and on some occasions I 
  saw great cumulus clouds that appeared to be floating in the smoke, just as 
  immense icebergs would float in the ocean. I was very much disappointed in the 
  view from Mount Shasta, on the one or two clear days that I had. Many thousands 
  of square miles of beautiful country were spread out before me, but I was so 
  high above that which was near, and so far from the rest, that the whole landscape 
  was flattened. I have seen many mountains not half so high where the landscape 
  was much more interesting.
At the top of Shasta Peak there is an old register that has been left there 
  for visitors to record their exploits in. Once it was a well bound volume, but 
  now it has no back and has lost many of its leaves. Visitors who ascend early 
  in the season find the book wet and frozen. In opening it it is mutilated, and 
  of course leaf after leaf is lost. I give a few of the entries, from which can 
  be inferred what the others are like, and how the persons felt who wrote them:
"1874, July 3 - Dimmis of Philadelphia - one-half way up and gave out. 
  GUIDE."
"1875, July 26 - Left Sisson's July 25, 1875, at 10.30 A. M. and arrived 
  at camp at 4 P. M. Left camp July 26 at 3.30 A. M. and arrived at the summit 
  at 8 A. M. Time, four and one-half hours. If any man weighting two hundred pounds 
  ever beats this time, and will call on the undersigned at Sacramento, he can 
  receive ample satisfaction. D. M. ADAMS."
"1877, June 25 - Left Sisson's June 25 in company with sixteen ladies and 
  gentlemen, who came as far as the camp. N. Kelsey and I stayed all night at 
  camp, and started for the summit at 4.45 A. M. Kelsey made about half the distance, 
  and then weakened and returned to camp. I arrived at the summit in company with 
  R. D. Hubbard, guide, at 11.30 A. M. View on the west side is fair, but totally 
  obscured on the east side by clouds. If any one catches me up here again I hope 
  them will pitch me over into the McCloud River. H. J. TODD, Oakland, Cal."
"1878, July 19 - I hope all fools will reach this place in due time. J. E. PUTNAM, 
  Yreka."
"1878, August 15 - Charles Lowley, of the Phoenix Mine, Napa County, California, 
  and Myron Gesford, of Napa City, ascended this mountain, to-day, for the first 
  and last time, so help us "Bob". We were our own guides."
"1878, September 14 - Aaron Bill, Shasta; James W. Shanklin, Oakland, California 
  - Alpha and Omega - hereby promise not to come again. FINIS."
These are fair samples of the inscriptions in the register.
For several days after I was ready for work the smoke was so dense below me 
  that I could not see twenty miles in any direction. I spent the time in making 
  such preparations as would insure success when it cleared, and in making occasional 
  excursions about the summit. In all of these I was alone, and did not dare to 
  explore the beautiful ice-caverns and crevasses that I peeped into. Many of 
  them were hundreds of feet deep any very beautiful, but not tempting enough 
  to allure me into them unless I had a rope and strong hands at the other end 
  of it to haul me out again. I think if safe to say that the nights are never 
  warm on Mount Shasta. During the time I was there the thermometer was at 100o 
  and a little over in the shade, at Sisson's during the day. The highest that 
  I had it on those days, with thermometer in the sun and out of the wind, was 
  67o. By four o'clock in the afternoon ice would form in the sun, and generally 
  by sundown the thermometer was at 25o. The coldest that I had it was 18o. When 
  the wind blew hardest it was warmest, probably because the warm air from the 
  valleys was blown up the sides of the mountain. It was the most comfortable 
  when there was no wind and the thermometer stood lowest. The cirrus clouds that 
  occasionally passed overhead seemed to be as high above me as they usually do 
  at the level of the sea. When a fog settled on the mountain the thermometer 
  generally went down to 32o or lower. The fog seemed to have congealed, and to 
  be microscopic crystals that formed a delicate coating for everything they touched. 
  If that wind blew, these particles began forming long frost crystals that stuck 
  out straight to the windward on everything exposed.
One lives fast at a great elevation. I weighed two hundred pound when I went 
  up, and lost fifteen pounds in the nine days that I remained. My pulse in repose 
  ranged from one hundred to one hundred and five per minute, and very little 
  exertion would send it up to one hundred and twenty. My head was clear, and 
  I had no difficulty in breathing. My appetite was fair; but, as my food was 
  all cold, except coffee and a little toasted cheese, I soon tired of it, and 
  craved hot bread and soup. I remained on the summit nine days and nights consecutively. 
  Richard Hubbard, a faithful guide and true man, remained four days, was one 
  day down (I was compelled to send him on business), and returned and stayed 
  four days. He worked continuously while on the mountain, and stood it splendidly. 
  His pulse was lower than mine, and his appetite first-rate. As an assistant 
  on such an expedition I do not know of his equal.
Thomas Sullivan, a fine-looking specimen of physical development, spent the 
  first night, and was so sick that he could remain no longer. His extremities 
  were cold, his pulse feeble, eyes blood-shot, and lips, nose, and ears purple. 
  Mr. Thomas D. Carneal, of Oakland, came and remained with me two nights and 
  a day. He was restless the first night, and suffered from cold hands and feet; 
  he rallied next day and expressed a desire to remain longer, but yielded his 
  place to Doctor McLean, of Oakland. Doctor McLean suffered some with cold, and 
  was a little affected in the head. He remained two nights and a day, and was 
  glad to leave. Randolph Random, a laborer, came up in the afternoon, and we 
  broke camp the next morning. He was sick and restless, just as Sullivan had 
  been, and was unable to do much the next morning, although he made a manly effort.
Mr. A. F. Rodgers, Assistant United States Coast Survey, speaking of his sojourn 
  here, says:
"1875, Tuesday, October 5 - By sunset the temperature had fallen to twenty-five 
  degrees, and it became necessary to go to bed to keep warm. I may here mention 
  a singular circumstance connected with our sojourn on the summit - every one 
  suffered with an intense headache, and no one could sleep; nor was any special 
  inconvenience experienced from the want of it. Mr. Eimbeck, Assistant United 
  States Coast Survey, who happened to visit the mountain while I was there, was 
  constantly affected with nausea, which he called sea-sickness, and ascribed 
  to the essayed the duties of cooking in these springs affected with symptoms 
  of fainting; and every one without exception suffered great inconvenience, no 
  doubt from the rarefied air of the summit. Whether this effect was increased 
  by any influence of the vapors is, I think, doubtful; personally I was not conscious 
  of any effect, even when standing among them, although I suffered while on the 
  summit, as every one did, from an unceasing and intolerable headache."
Friday, August 1, proved to be the day I had been waiting for. The wind had 
  hauled to the northward during the night, and the smoke had vanished as if by 
  magic. At sunrise, I turned my telescope in the direction of Mount Lola, and 
  there was the heliotrope, one hundred and sixty-nine miles off, shining like 
  a star of the first magnitude. I gave a few flashes from by own, and they were 
  at once answered by flashes from Lola. Then turning my telescope in the direction 
  of Mount Helena, there, too, was a heliotrope, shining as prettily as the one 
  at Lola. My joy was very great; for the successful accomplishment of my mission 
  was now assured. As soon as I had taken a few measures, I called Doctor McLean 
  and Hubbard to let them see the heliotrope at Mount Helena, one hundred and 
  ninety-two miles off, and the longest line ever observed in the world. In the 
  afternoon the smoke had arisen, and Helena was shut out; but on the following 
  morning I got it again, and my mission on Mount Shasta was finished. The French 
  have been trying for some years to measure, trigonometrically, some lines from 
  Spain across the Mediterranean to Algiers; they have only recently succeeded, 
  and it has been a source of great satisfaction to French geodesists. Their longest 
  line is one hundred and sixty-nine miles. The line from Mount Shasta to Mount 
  Helena is one hundred and ninety-two miles long, or twenty-three mile longer 
  than their longest. And the glory is ours; for America, and not Europe, can 
  boast of the largest trigonometrical figures that have ever been measured on 
  the globe.
On Sunday morning, August 3d, the north wind had died out, and the smoke had 
  again enveloped everything. I saw that nothing else would be seen for many days, 
  and at once set about packing up. By nine o'clock everything was packed. We 
  made a light sled, adapted for use both on the sow-fields and the rocky, mountain 
  slopes, and with it made two trips to the edge of the great snow-field, carrying 
  about three hundred and thirty pounds at a time. By noon we had the last of 
  our outfit at the brink of the snow precipice, where we did them all up in packages 
  which were securely lashed, and as nearly round as we could make them. The sow-field 
  stretched out before us, beautifully white and ever. At the top there was, first, 
  a precipitous descent of about three hundred feet; then away it stretched for 
  about two miles, in which distance it had a descent of about three thousand 
  feet. The plan was to let the packages loose, to go as they would, and while 
  Hubbard rolled the first one to the brink and let it go, I stood on a projecting 
  point and watched it. The snow lying at the top like a crest of an immense wave, 
  each package had a perpendicular distance of about three hundred feet to fall 
  after leaving the brink before it touched anything. Its velocity was very great 
  by the time it reached this point, and as soon as it hit the snow, away it bounded. 
  Sometimes a slight inequality would incline one to the right or left and so 
  they went until, rounding an intervening hill, they were lost to sight. As soon 
  as the last package had gone out of sight, we strapped the instruments on our 
  backs and began the descent. We had about forty pounds each, and had to pack 
  it about a mile along the ridge before we came to a place where the snow was 
  not too steep to slide on. When we found such a place, each put a gunny-sack 
  on the snow and sat down on it. The alpenstock was next placed under one arm, 
  so as to project to the rear and form a brake. Than a slight motion with the 
  feet, and we were off like a shot. I have had many pleasant rides, but for rapidity 
  and ease of motion this beat them all. I had perfect control of myself by means 
  of my alpenstock. Every foot of descent was bringing me into a denser atmosphere, 
  and the effect of the whole was that of a very delightful stimulant. 
This delightful ride terminated just where the packages stopped rolling. Looking 
  back, I could follow with my eyes the track I had made in the snow, and away 
  up toward the place where I had started I saw my gunny sack. In the keen enjoyment 
  of my ride I had not missed it, but a preliminary examination satisfied me that 
  I had lost not only the gunny sack, but the seat of my trousers, and I congratulated 
  myself in having escaped so easily. The packages had all stopped near each other, 
  and we soon hauled them to a place from which we could pack them on horses. 
  It was four o'clock when this was finished, and leaving Hubbard to spend the 
  night with some hunters that we found on the mountain, I completed my day's 
  work and the expedition to Shasta by walking to Sisson's, a distance of about 
  twelve miles, and arrived there before dark, successful in my undertaking, pleased 
  with my trip, and glad that it was over.
