About this map

The Warm Springs Indian Reservation landscape is defined by the prominent Sidwalter Buttes and a network of high-desert water sources and ridges. A significant historical marker is the Old Indian Reservation Boundary (Gumsey Line 1882) which cuts across the northwestern corner, providing a specific reference to late 19th-century land management and surveying. The terrain transitions from the elevations of Long Ridge down to the riparian zones of the Warm Springs River and Warm Springs Meadow.

Evidence of local land use and infrastructure appears at Schoolie Pasture and a lone Lookout tower perched near the buttes. The hydrology of the area is represented by numerous named springs such as Big Spring and Nellie Spring, alongside the drainage of South Fork Badger Creek and the southern Mill Creek flowing through Mill Creek Flat. This 1980s field check records the geographic features and jurisdictional lines of this section of Wasco County before subsequent modern developments.
