2010 Map of Slack Mountain

About this map

Slack Mountain rises as a central landmark in this high-desert Owyhee County landscape, where a sophisticated network of seasonal water management defines the territory. The 2010 survey reveals a high concentration of livestock-related water features, including Hagberry Dam and Hackberry Reservoir in the north, and Antelope Reservoir to the southwest. This area is characterized by dramatic topographic shifts, from the deep incisions of Cow Valley Canyon and Cougar Canyon to the broad, flat expanses of Boni Table and June Grass Table. The presence of named springs like Frying Pan Spring and Dry Lake Spring alongside remote roads such as Mud Flat Rd and Juniper Mountain Rd illustrates the vital water sources required for range management in this arid Idaho interior.
