2023 Map of Dickerson Flat

About this map

Dickerson Flat and the surrounding high desert of Deschutes County are characterized by a series of distinct volcanic ridges and isolated water sources. This 2023 survey by the U.S. Geological Survey captures the specialized landscape of central Oregon, where terrain features like Black Ridge, Moonshine Ridge, and Berger Ridge dictate the movement of both wildlife and the limited local road network. The presence of Whiskey Spring, Pumice Waterhole, and Two Post Lake suggests the vital role of these small, specific points of hydration in an otherwise arid environment.
