About this map

Chalk Hills rise within this Owyhee County landscape, defined by a network of drainage features and ranching activity. The terrain is deeply incised by Twentymile Gulch, Halfway Gulch, and the prominent Waterspout Draw. Water resources are localized along Shoofly Cr and Poison Cr in the north, while the southern reaches are marked by the canyons of Little Jacks Cr and Big Jacks Cr.

Settlement is sparse and centered on livestock operations, with Parker Ranch and Al Sadie Ranch serving as primary landmarks in this high-desert environment. Transportation follows established paths such as Shoöfly Rd and Poison Creek Rd, reflecting the functional infrastructure required for remote ranching. The map illustrates a specialized land-use pattern where named features like Cattle Dr highlight the enduring cattle industry of the Idaho backcountry.
