About this map

Chalk Hills defines the high-desert topography of this Owyhee County landscape, where water and transit have long dictated the patterns of human activity. The terrain is deeply inscribed by seasonal drainages such as Waterspout Draw, which feeds into the larger system of Little Jacks Creek and Big Jacks Creek. These watercourses provided the essential anchor for ranching operations in a dry environment, supporting established sites like Parker Ranch and the Al Sadie Ranch to the south.

Transportation routes through this area follow the natural contours of the land, with Shoofly Rd and Poison Creek Rd serving as the primary arteries through the sagebrush and scrub. The naming of Cattle Dr speaks to the region's enduring agricultural identity. North of the hills, Shoofly Creek winds toward the Snake River plain, marking the transition from the high-plateau draws to the lower basin.
