2013 Map of Castro Table

About this map

The high plateau country of Owyhee County is defined by prominent basaltic mesas and seasonal watercourses on this 2013 survey. Notable landforms like Boni Table, June Grass Table, and Black Table rise above the drainage systems of Nickel Cr and Deep Cr. This area reflects the grazing and ranching heritage of the Idaho backcountry, centered around the Castro Ranch and the open expanse of Ben Mills Flat. Isolated water sources such as Camp Spring and Swisher Spring provide critical points of interest in this arid landscape. The map shows a network of remote corridors like Grasshopper Rd, which connects these elevated tables to the larger terrain of Bull Gulch and the Long Meadow Cr drainage.
