2012 Map of West Thumb

About this map

Yellowstone Lake dominates this 2012 survey, its western shoreline defined by active thermal features and the established visitor hubs of Grant Village and West Thumb. This map documents a high concentration of hydrothermal activity along the water's edge, particularly within the West Thumb Geyser Basin and Potts Hot Spring Basin. Geologists and researchers can locate specific thermal landmarks such as Abyss Pool, Overhanging Geyser, and the Twin Geysers. The landscape transitions from the deep waters near Bluff Point and Pumice Point to the intricate network of inland drainages including Arnica Cr and Little Thumb Cr. Further south, the settlement of Grant Village serves as a modern anchor near the mouth of Solution Cr, while the historic Howard Eton Trl provides a trace of backcountry travel through the northern timber.
