The Dearborn River snakes through this high-altitude landscape in Lewis and Clark County, joined by a dense network of mountain tributaries. The terrain is defined by dramatic elevation changes, notably at Welcome Pass and Elk Pass, which serve as natural transit points between drainages. The Grassy Hills dominate the southeastern quadrant, where the Grassy Hills Cabin stands as a solitary named structure in an otherwise undeveloped area.
