"[Lot of 2] Geological Map of Portions of Wyoming, Idaho and Utah [and] Economic Map of Portions of Wyoming, Idaho and Utah", U.S. Department of Interior

The first map was one of six included in Hayden's 12th Annual Report published in 1883. It is a handsome and colorful map that largely covers 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, Rawlings is at lower right with a portion of the Union Pacific Railroad detailed. It 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. It locates Blackfoot, Rose Fork Agency (Fort Hall), John Gray's Lake, Caribou, the Wind River or Shoshone Reservation, and much more. Taylor's Bridge on the Snake River pre-dates Idaho Falls.

Second map is also one of the six maps that were included in Hayden's 12th Annual Report published in 1883. It is a beautifully executed chromolithographed map that details the land types of the region. The map covers the area from Jackson Lake and the Tetons in the north and south to below Bear Lake, Logan and Robinson's Ferry on the Green River. It extends from Blackfoot, Idaho in the west to Rawlings, Wyoming in the east. A color/style legend identifies land types including arable land, grass, sage, forest, and rock. Coal deposits are identified via red over printed lines. It is a very detailed chart drawn on a scale of 1 inch per 8 miles with geology by A.C. Peale, Orestes St. John, and F.M. Endlich.
