About this map

Ross Lake and a series of ephemeral water bodies define this corner of Owyhee County, where the high desert landscape dictates a pattern of seasonal grazing and sparse settlement. The map reveals a drainage network centered on Ross Slough, which connects several distinct basins including Henry Lake, Juniper Lake, and the aptly named Mud Flat. These features, along with Rough Lake and Bybee Reservoir to the north, illustrate how water is managed and gathered in this arid environment.

Human presence is marked by isolated outposts like Pleasant Valley and the infrastructure required to traverse this open range. Routes such as Pleasant Valley Rd and the Riddle Ranch Rd provide the primary access to the region's vast ranching allotments. Farther into the backcountry, the Garaf Trl and various unnamed tracks suggest a landscape utilized for livestock and land management, where natural landmarks like Yatahoney Cr and Shoofly Cr serve as vital identifiers for navigation.
