About this map

Upper Geyser Basin serves as the focal point of this 2015 study, capturing the dense concentration of geothermal features that have drawn travelers for over a century. The intricate network of hydrothermal activity is meticulously documented, from the world-famous Old Faithful Geyser to the Lion Group and the Myriad Group Springs. The Firehole River threads through these basins, passing landmarks such as Biscuit Basin and the Sinter Plain.

Beyond the primary geyser fields, the map traces the high-country transition across the Continental Divide. Prominent trails like the Mallard Creek Trail and the Kepler Cascade Ski Trail provide access to more secluded water bodies, including Mallard Lake and Teal Lake. The inclusion of the Lone Star Geyser Basin to the south and the crossing at Grants Pass illustrates the connectivity of this thermal landscape within the vast protected wilderness of Yellowstone National Park.
