2017 Map of Chalk Hills

About this map

The Chalk Hills rise as a prominent landform in this high-desert portion of Owyhee County, defined by a network of seasonal drainages and remote access roads. This 2017 survey details the essential topography for land management and navigation in an area characterized by deep erosional features like Twentymile Gulch and Waterspout Draw. The landscape is largely dictated by the passage of water through intermittent streams such as Shoofly Cr and Poison Cr, which eventually give way to the more substantial canyons of Little Jack Cr and Big Jack Cr to the south.
