1948 Map of Perjue Canyon

About this map

Perjue Canyon Creek and Shoofly Creek carve through this Owyhee County landscape, illustrating the drainage patterns of the high desert shortly after World War II. The terrain is defined by dramatic erosional features like the Chalk Hills and the expansive Mud Flat, where the lack of dense settlement emphasizes the region's cattle and range character. Transportation in the late 1940s relied on unpaved routes like Castle Creek Road and Mud Flat Road, which provided essential links through the arid draws and gulches. Numerous benchmarks, such as BM 3815 and BM 3548, are meticulously recorded across the quadrangle, reflecting the detailed plane-table work performed by the Geological Survey in 1947 to map these complex landforms like Twentymile Gulch and Vinson Wash.
