2020 Map of Triangle Flat

About this map

Triangle Flat and the adjacent Long Valley define the high-plateau geography of this Owyhee County landscape, where the seasonal flow of water dictates human activity. The small settlement of Triangle sits at the junction of Triangle Rd and Antelope Ridge Rd, serving as a focal point for the surrounding ranching and range land. Water management is central to the area's history, evidenced by the Twin Valley Reservoir and numerous named water sources like Florence Spring, Chimney Spring, and Hardman Spring. The presence of the Josephine Ranch Airport near Josephine Creek underscores the necessity of aerial access in this expansive terrain. This 2020 update traces the network of primitive routes and ranch-to-market roads, including Flint Rd and Flint Creek Rd, which follow the natural contours of the land through Rose Ridge and down toward the many creek beds that drain the basin.
