2017 Map of East Basin Creek

About this map

The Salmon River carves a significant course through the southern portion of this landscape, forming a prominent geological feature at Mormon Bend. This section of the Challis National Forest is defined by an intricate drainage system including Hay-Knapp Creek and the W Fork Yankee Fork. The mapping of high-elevation water bodies like East Basin Lake and the various tributaries such as Sawmill Cr and Upper Harden Cr illustrates the complex hydrology of the Salmon River Mountains. Surveyed in the late 2010s, the map provides a look at the wilderness and forest management boundaries, including numerous protected blocks and township divisions that dictate the land use in this remote part of Custer County.
