2020 Map of Sphinx Mountain

About this map

Sphinx Mtn and The Helmet dominate this high-elevation landscape within the Beaverhead National Forest and Gallatin National Forest. This 2020 survey details a complex network of ridgelines and water sources, most notably the Inspiration Divide which snakes through the central terrain. The map documents the high-country hydrology of the Madison Range, including the headwaters of McAtee Cr, Indian Cr, and the S Fork W Fork Gallatin River. Significant landmarks like Yellowmule Cabin and Eglise Rock are situated among the peaks, while named drainage features such as McAtee Basin and Buck Ridge illustrate the area's geological character. This modern topographic record captures the established trail systems and forest boundaries that define this part of Madison County, providing a precise look at the drainage patterns of Pioneer Mountain and Circle Mtn.
