About this map

The Challis National Forest dominates this section of Custer County, where high-elevation basins and steep canyons create a complex drainage system feeding the East Fork Salmon River. The landscape is defined by its dramatic verticality, from the depths of Spar Canyon in the northeast to the broad, elevated flats of Ziegler Basin and Woods Basin. These basins likely served as critical high-country grazing or transit areas, connected by ephemeral water sources like Alkali Springs and LMB Spring.

Water management and natural flow are central to the area's geography, with Spud Cr and Spud-Marco Creek carving through the western slopes. Evidence of the region's erosion patterns is visible in the numerous named gulches, such as Cherry Gulch, Monument Gulch, and Frisch Gulch, which drain toward the river valley. This 2017 survey provides a high-resolution look at the intricate topography and creek networks within the public lands of central Idaho.
