1981 Map of Thermopolis

About this map

The Bighorn River and Wind River define the thermal and industrial character of this central Wyoming region during the early 1980s. At the heart of the map, Thermopolis and East Thermopolis sit adjacent to Hot Springs State Park, a site long-famed for its geothermal activity. The geography is marked by the sharp transition from the Owl Creek Mountains and the northern reaches of the Wind River Indian Reservation to the resource-rich basins. The map documents an active energy landscape, highlighting the Maverick Spring Dome Oil Field and the Burlington Northern railroad corridor, which served the coal and agricultural interests of the valley. Smaller outposts like Gebo, Embar, and Hamilton Dome reveal the distribution of ranching and mining communities that established the local economy.
