About this map

Boni Table and June Grass Table dominate this Owyhee County landscape, where the high, flat plateaus are separated by a complex network of drainages. The area is defined by its water sources, including Camp Spring and Bower Reservoir, which likely served as critical infrastructure for local ranching operations. Names like Star Ranch Table and Nickel Creek Pocket suggest a history of seasonal grazing and livestock management on these elevated landforms.

Deeply incised canyons carved by Deep Creek and Pole Cr create dramatic relief against the flat-topped tables. Toward the southern extent, Ben Mills Flat and Bull Gulch provide further evidence of the region's topographically varied character. The map traces the winding paths of Swisher Cr and Moonshine Cr, reflecting a landscape where every drainage and spring has a specific local name, vital for navigating this remote corner of southwestern Idaho.
