2012 Map of Old Faithful

About this map

Morning Glory Pool and the Sinter Plain characterize this high-elevation geothermal landscape along the Firehole River. In 2012, this survey documents the intricate network of hydrothermal features centered on Biscuit Basin, where concentrated thermal activity is evidenced by labels such as Jewel Geyser, Sapphire Pool, and Silver Globe. The map captures the hydrological complexity of the region, from the dramatic Mystic Falls on the Little Firehole River to the quiet elevation of Mallard Lake. High-altitude transitions are marked by Grants Pass and the Cement Hills, providing a detailed look at the backcountry terrain surrounding these famous thermal basins. The distribution of springs like Punch Bowl Spring and Asta Spring illustrates the persistent volcanic legacy of the Teton County wilderness.
