1990 Map of Sheep Creek Divide

USGS Topo · Published 1990

About this map

The Imnaha River carves through a deeply dissected landscape of high ridges and narrow creek basins within the Wallowa National Forest. This high-country region is structured by massive geologic spines, including the central Sheep Creek Divide and the prominent Dead Horse Ridge. Human presence in this isolated terrain is sparse, centered on vital outposts like the College Creek Ranger Station and the Imnaha Grange.
