2020 Map of Dickerson Flat

About this map

Dickerson Flat and the surrounding high desert of Deschutes County are defined by a network of seasonal water sources and volcanic terrain in this modern survey. The landscape is characterized by prominent basalt and pumice features, including Black Ridge, Moonshine Ridge, and the distinct formation at Whiskey Rock. Transportation through this arid region relies on the unpaved corridor of Fox Butte Rd, which provides access to traditional watering points like Pumice Waterhole and Whiskey Spring. In the southeast, Two Post Lake sits near the base of Berger Ridge, illustrating the subtle drainage patterns of the high plateau. This map reveals how historical water naming conventions—referencing moonshine and whiskey—persist in the modern geographic nomenclature of the Oregon interior, marking a landscape that remains sparsely developed and largely defined by its geological character.
