2020 Map of Mormon Mountain

About this map

The Payette National Forest and Salmon National Forest meet in this high-elevation corner of Valley County, where the landscape is defined by the massive divide of Big Creek Ridge. This 2020 survey documents a complex drainage network where the headwaters of Canyon Creek and Rush Creek carve deep into the Idaho wilderness. Landmarks like Sheep Horn Mtn and Mormon Mtn provide fixed points for navigating the steep terrain between Lobauer Basin and Browns Basin. The map detail captures the remote character of the interior mountains, showing no major roads or settlements, only the intricate topography and named water features like Telephone Creek and Lewis Cr that have guided packers and rangers through these woods for generations.
