About this map

The Warm Springs Indian Reservation dominates this 1980s landscape, where its historic boundaries meet the high-elevation terrain of the Cascade Range. The map illustrates the divergence of the Old Indian Reservation Boundary (Campbell Line 1901) and the earlier Old Indian Reservation Boundary (Rumsey Line 1882), marking a significant legal and territorial transition within Wasco Co and Jefferson Co.

Hydrological features are abundant, centered around Boulder Lake and the drainage systems of North Fork Boulder Creek and South Fork Boulder Creek. Distinctive volcanic landmarks like Badger Butte, Cinder Cone, and Lookout Butte overlook the plateau, while smaller water bodies such as Lake Sarah, Francis Lake, and Island Lake are scattered across the southern reaches. Local infrastructure is minimal, consisting of forest routes like Blue Lake Road and Harvey Lake Road, alongside a remote Campground and the isolated clearing of Peters Pasture.
