About this map

The high alpine country of the Elkhorn Mountains dominates this 2020 map, revealing a landscape defined by steep drainages and glacial lakes. The settlement of Bourne sits at the confluence of Cracker Cr and Little Cracker Cr, while the larger town of Sumpter is positioned further south at the junction of McCully Fork and the Sumpter Reservoir. This area of the Whitman National Forest is crisscrossed by an extensive network of specialized routes, including the Silver Creek Snowmobile and the Spaulding Ridge Snowmobile trails, which follow the contours of the high ridges.

Water resources are prominent, from the protected waters of the North Fork John Day Wild and Scenic River in the northwest to high-altitude basins like Western Union Basin and Mayflower Meadow. Significant water bodies including Rock Creek Lake, Killamacue Lake, and Summit Lake are tucked along the Elkhorn Crest, highlighting the dramatic elevation changes that once supported historical mining and now define the regional recreation network.
