2023 Map of Triangle Flat

USGS Topo · Published 2023

About this map

Triangle Flat and the surrounding high country of Owyhee County are defined by a network of seasonal drainages and remote ranching infrastructure. This modern survey illustrates the rugged drainage patterns of Rock Creek and Josephine Creek, which carve through the plateau toward Twin Valley Reservoir. The landscape is dotted with critical water sources for high-desert ranching, including Hardiman Spring, Chimney Spring, and Florence Spring, essential landmarks in this arid environment. The small settlement of Triangle sits at the junction of Triangle Rd and Antelope Ridge Rd, serving as a central point in a territory otherwise dominated by topographical features like Rose Ridge and the expansive Long Valley. The presence of the Josephine Ranch Airport in the southern portion of the quadrangle highlights the continued reliance on private aviation for access to these isolated Idaho ranchlands.
