I left Great Salt Lake a good deal confused as to what state of things existed there—and sometimes even questioning in my own mind whether a state of things existed there at all or not. But presently I remembered with a lightening sense of relief that we had learned two or three trivial things there which we could be certain of; and so the two days were not wholly lost. For instance, we had learned that we were at last in a pioneer land, in absolute and tangible reality.

From Orion: 4 P. M., arrived on the summit of “Big mountain,” 15 miles from Salt Lake City, when the most gorgeous view of mountain peaks yet encountered, burst on our sight.

From Burton Echo Kanyon, August 24th and The End—Hurrah! August 25th.

Twain, of course, had a different impression of the "Destroying Angel" Ephe Hanks than did Burton:

From Burton:  23d August. Fort Bridger

(The City of the Saints)

From Orion: Sunday, Aug. 4.—Crossed Green River. It is something like the Illinois, except that it is a very pretty clear river. The place we crossed was about 70 miles from the summit of the South Pass. Uinta mountains in sight, with snow on them, and portions of their summits hidden by the clouds. About 5 P. M arrived at Fort Bridger, on Black’s Fork of Green river, 52 miles from the crossing of Green river, about 120 miles from the South Pass, and 1025 miles from St. Joseph.

From Orion:

In the night we sailed by a most notable curiosity, and one we had been hearing a good deal about for a day or two, and were suffering to see. This was what might be called a natural ice-house. It was August, now, and sweltering weather in the daytime, yet at one of the stations the men could scape the soil on the hill-side under the lee of a range of boulders, and at a depth of six inches cut out pure blocks of ice—hard, compactly frozen, and clear as crystal! (Roughing It)

From Roughing It:

From Orion: Friday, Aug. 2.—3 o’clock, A. M., passed over North Platte bridge, 760 miles from St. Joseph. 2 P. M., reached “Sweet water” creek, “Independence Rock,” the “Devil’s Gap,” the “Cold Spring,” an ice water spring, issuing near one of the Stations,. Now, or at any time of the year, the men at this Station by scraping off the soil, sometimes only to the depth of six inches, can cut out pretty, clear, square blocks of ice. This “cold spring” is 36 miles from “Independence Rock,” and 847 miles from St. Joseph.

After dinner we climbed to the yellow pines. This afternoon passed, near La Pierelle station, the little canon in which the Express rider was last night when a bullet from Indians on the side of the road passed through his coat. About 2½ hours before the station keeper at La Parelle had fired four times at one Indian. At noon we passed a Mormon train 33 wagons long. They were nooning.

Thursday, Aug. 1. Found ourselves this morning in the “Black Hills,” with “Laramie Peak,” looming up in large proportions. This peak is 60 miles from Fort Laramie, which we passed in the night. We took breakfast at “Horseshoe” station, forty miles from Fort Laramie, and 676 miles from St. Joseph.  - Clemens
