2013 Map of Triangle Flat

About this map

Triangle sits in the high desert of Owyhee County, marking a sparse ranching landscape where water sources dictate the geography of human activity. The terrain is defined by dramatic elevation changes, moving from the broad expanse of Triangle Flat and Long Valley toward the prominent Rose Ridge in the south. This area is heavily dependent on a network of named springs, including Florence Spring, Hardiman Spring, and Chimney Spring, which feed into the seasonal flow of Josephine Cr and Triangle Cr. The map reveals the infrastructure of remote range management, highlighting the Josephine Ranch Airport as a vital link for this isolated community. Historic transportation routes like Flint Rd and Triangle Rd connect the scattered reservoirs, such as Spencer Reservoir and Twin Valley Res, which serve as critical landmarks in a region dominated by vast open grazing lands and rugged drainage basins.
