"[Lot of 2] Geological Map of Portions of Wyoming, Idaho and Utah [and] Part of Central Wyoming", Hayden, Ferdinand Vandeveer
Subject: Western United States
Period: 1877-79 (circa)
A. Geological Map of Portions of Wyoming, Idaho and Utah, circa 1879, printed color (36 x 20.5"). This was one of ten maps included in Hayden's 12th Annual Report published in 1883. It is a handsome and colorful map that focuses on part of Idaho eastward to the Sweetwater Range. Topography and hydrology are nicely developed and an abundance of towns and villages are shown. Bear Lake is at lower left bordering Idaho and Utah, and Rawlings is at lower right with a portion of the Union Pacific Railroad detailed. The map locates wagon roads, trails, sand dunes, and has fine watershed details. Mining activity is clearly shown in place names like Miner's Delight, Camp Stambaugh, Atlantic City, etc. Other place names include Blackfoot, Rose Fork Agency (Fort Hall), John Gray's Lake, Caribou, and the Wind River or Shoshone Reservation. Taylor's Bridge on the Snake River pre-dates Idaho Falls. Condition: Issued folding, now pressed and backed with archival tissue. Strong color and full, original margins. A little marginal toning on folds, short marginal split on one fold, supported by tissue backing. Re-margined at left to extend narrow margin at binding trim. (A)
B. Part of Central Wyoming, dated 1877, black & white (33 x 23"). A very detailed map that displays the full course of the Sweetwater River, South Pass, etc. and depicts trails throughout the region. Wheat draws attention to the map's value to students of the Fur Trade and overland emigrant routes. Remarkable detail is shown with contour intervals at 200 feet and a scale of 4 miles = 1 inch. The map extends from part of the Wind River Reservation south to Rawlins. Old wagon roads, trails and the Union Pacific Railroad are featured. Condition: Issued folding, now pressed and backed with archival tissue to repair and reinforce some fold separations. There is a hint of toning along a few folds, and a few minor spots at the bottom of the image. (B+)
