About this map

Castro Table and a series of expansive basaltic plateaus define this corner of Owyhee County, where the high desert landscape is deeply incised by drainages like Deep Creek and Nickel Creek. This modern survey reveals a region shaped by ranching and water management, evidenced by features such as Star Ranch Table and Bower Reservoir in the northern reaches. The presence of Ben Mills Flat and named pockets like Nickel Creek Pocket suggest a history of localized grazing and land use within the breaks of the tablelands.

Remote drainages with evocative names such as Moonshine Creek, Skunk Creek, and Cowboy Creek feed into the larger creek systems, illustrating the complex hydrology required to sustain life in this arid environment. Transportation is sparse, limited primarily to the unpaved Grasshopper Rd crossing the southern sections. Notable landmarks including Flatiron Butte and Big Point provide significant orientation points for navigating the high-relief terrain between the level surfaces of June Grass Table and Black Table.
