The route over the Rocky Mountains started from Fort Laramie, through South Pass and into Salt Lake City. Sam and Orion passed by Fort Laramie at night, from August 1 to August 5th. Richard Burton took 2 weeks to complete this leg of his journey, from August 14 to August 28.

August 4 Sunday – 10 th day out – Sam and Orion ate a memorable meal at Green River station—fresh antelope steaks, hot biscuits, and good coffee. Years later they said it was the only meal on the trip between St. Joseph and Salt Lake that they were “really thankful for.” A stagecoach inn state park and museum now invites tourists in Fairfield, Utah. Orion’s journal [RI 1993, 771]:

August 5 Monday – 11 th day out – Orion’s journal:
52 miles further on, near the head of Echo Canyon, were encamped 60 soldiers from Camp Floyd. Yesterday they fired upon 300 or 400 Utes, whom they supposed gathered for no good purpose.  
4 P.M., arrived on the summit of “Big Mountain,” 15 miles from Salt Lake City, when the most gorgeous view of mountain peakes yet encountered, burst on our sight.

August 6 Tuesday – 12 th day out – The brothers rested in Salt Lake City. Sam and Orion’s layover at Salt Lake allowed them to bathe and stock up for the remainder of the trip. After donning white shirts, the pair was introduced to Brigham Young (1801-1877). Sam described Young as “a quiet, kindly, easy-mannered, dignified, self-possessed old gentleman…” [Roughing It, Ch. 13]. Note: no entry in Orion’s journal for this day.
