About this map

The Warm Springs Indian Reservation dominates this 1980s landscape, where historical borders and high-elevation hydrology intersect. A significant feature is the Old Indian Reservation Boundary (Rumsey Line 1882), which cuts through the mountainous terrain between Jefferson, Wasco, and Marion counties. This line serves as a reminder of the complex land tenure and surveying history of the Oregon Cascades.

Water resources are densely concentrated in the western portion of the sheet, characterized by a series of high-altitude lakes including Boulder Lake, Trout Lake, Francis Lake, and Lake Sarah. The area's topography is defined by prominent peaks such as Badger Butte and Lookout Butte, with drainage provided by the forks of Boulder Creek and the southern Shitike Creek. A remote Pack Trail and several campgrounds indicate the area's transition toward recreational use in the late 20th century.
