1956 Map of West Thumb

USGS Topo · Published 1965

About this map

Yellowstone Lake (West Thumb) serves as the focal point for this mid-century survey of the volcanic heart of the Wyoming backcountry. The landscape is defined by the hydrologic drama of the Continental Divide, where water separates toward the Pacific and Atlantic basins via the Lewis River and De Lacy Creek. Geothermal activity is prominent throughout the terrain, concentrated at the West Thumb Geyser Basin and the Potts Hot Spring Basin, as well as the more remote Heart Lake Geyser Basin near the base of Mount Sheridan.
