These two maps were issued in Hayden's 12th Annual Report for 1879, but not published until 1883. The maps are identical in size and scale, and show all land from the Green River Basin in the east to the Bear River Range to the west. They extend north to include part of Gary's Lake and details the Aspen, Salt River and Wyoming Ranges in the north, and extends south below Bear Lake to Logan. The maps further locates numerous settlements and includes Fremont’s Lake adjacent to today's Pinedale. In addition to the topographical features found on both maps, the geological map uses bold color and pattern to depict 22 different geologic types including recent deposits, sedimentary formations, and metamorphic rocks. Survey work completed by Henry Gannett. A nice pair of maps that is uncommonly seen together.
