Thursday July 18, 1861:  Sam and Orion depart St. Louis on the Sioux City for St. Joseph, Missouri:

July 26.—Left St. Joseph. Started on the plains about ten miles out. The plains here are simply prairie.

July 27. Crossed the Nebraska line about 180 miles from St. Joseph. Here we saw the first Jack Rabbit.

July 28. Fort Kearney

Tuesday, July 30. Arrived at the “Crossing” of the South Platte, alias “Overland City,” alias “Julesburg,” at 11 A. M., 470 miles from St. Joseph. Saw to-day first Cactus. 1:20 P. M. across the South Platte.

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.

"We had now reached a hostile Indian country, and during the afternoon we passed Laparelle Station, and enjoyed great discomfort all the time we were in the neighborhood, being aware that many of the trees we dashed by at arm’s length concealed a lurking Indian or two. 

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,

During the afternoon we passed Sweetwater Creek, Independence Rock, Devil’s Gate and the Devil’s Gap. The latter were wild specimens of rugged scenery, and full of interest—we were in the heart of the Rocky Mountains, now. And we also passed by “Alkali” or “Soda Lake,” and we woke up to the fact that our journey had stretched a long way across the world 

Saturday, Aug. 3. Breakfast at Rock Ridge Station, 24 miles from “Cold Spring,” and 871 miles from St. Joseph.   A mile further on is “South Pass City” consisting of four log cabins, one of which is the post office, and one unfinished.

Two miles beyond South Pass City we saw for the first time that mysterious marvel which all Western untraveled boys have heard of and fully believe in, but are sure to be astounded at when they see it with their own eyes, nevertheless—banks of snow in dead summer time. We were now far up toward the sky, and knew all the time that we must presently encounter lofty summits clad in the “eternal snow” which was so common place a matter of mention in books, and yet when I did see it glittering in the sun on stately domes in the distance and knew the month was August and that my coat was hanging up because it was too warm to wear it, I was full as much amazed as if I never had heard of snow in August before. Truly, “seeing is believing”—and many a man lives a long life through, thinking he believes certain universally received and well established things, and yet never suspects that if he were confronted by those things once, he would discover that he did not really believe them before, but only thought he believed them.

At the Green river station we had breakfast—hot biscuits, fresh antelope steaks, and coffee—the only decent meal we tasted between the United States and Great Salt Lake City, and the only one we were ever really thankful for. Think of the monotonous execrableness of the thirty that went before it, to leave this one simple breakfast looming up in my memory like a shot-tower after all these years have gone by!

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.

Monday, Aug. 5.—52 miles further on, near the head of Echo Canon, were encamped 60 soldiers from Camp Floyd. Yesterday they fired upon 300 or 400 Utes, whom they supposed gathered for no good purpose. The Indians returned the fire, when the soldiers chased them four miles, took four prisoners, talked with and released them, and then talked with their chief. Echo Canon is 20 miles long, with many sandstone cliffs, (red) in curious shapes, and often rising perpendicularly 400 feet.

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.

Arrived at Salt Lake City at dark, and put up at the Salt Lake House,.

Wednesday, August 7.  Depart Salt Lake City early morning.
