1983 Map of Dickerson Flat

USGS Topo · Published 1983

About this map

Dickerson Flat anchors this high-desert landscape in Deschutes County, revealing a terrain defined by volcanic features and isolated water sources. As a provisional survey based on 1970s aerial photography and 1980 field checks, the map highlights the essential markers of the high plains where topography often dictates movement. Distinctive basalt and pumice-related features such as Moonshine Ridge, Black Ridge, and the Pumice Waterhole suggest a geologic history that shaped the local ranching and exploration patterns. Evidence of human activity and resource management is sparse but significant, concentrated at locations like Corral/Dickerson Well and Spicer Flat. These named locations, along with natural landmarks like Whiskey Rock and the transient Dry Lake, serve as the primary navigational aids in an area where seasonal water from Whiskey Spring was once critical for survival.
