[Wagner-Camp 262a:1, Wheat Trans-Miss Maps 823]. From Wagner-Camp, this map was from the Pacific Railroad Reports issued in 1855 Volume II designated by 33d Congress: 2d Session, Senate Document 78. Serial 759 and House Document 91. Serial 792. Volume II consisted of seven reports and Edward Griffin Beckwith (1818-1881) wrote the Section 2 report of the survey along the line of the 41st parallel. In 1853, Beckwith was part of a survey party led by Capt. Gunnison to explore the 38 to 39 parallels. When Gunnison and others were killed by Ute Indians along the Sevier River, Captain Beckwith took charge of the survey party and returned to Salt Lake City for instructions. It was determined that the lower latitude routes were infeasible and Beckwith was given permission to survey along the 41 parallel from the Salt Lake to the Pacific. He started out in May, 1854 and the survey routes recommended generally follow the actual construction of the trans-continental railroad. (Inventory #: 13563)
