2017 Map of Purjue Canyon

About this map

Purjue Canyon and the surrounding drainage basins of Owyhee County are defined by a complex network of seasonal waterways and primitive access routes. This 2017 survey shows a landscape managed through the Public Land Survey System, marked by township boundaries like t7s r2e and t7s r3e. The topography is shaped by the descent of Poison Cr and Shoofly Cr as they cut through the high desert plateau. Human presence is primarily indicated by a sparse network of rangeland roads, including Poison Creek Rd and Castle Creek Rd, which provide essential access for ranching and resource management. Notable geographic landmarks such as Twentymile Gulch demonstrate the erosional patterns of the Owyhee Front, where small tributaries have carved distinct features into the volcanic and sedimentary layers over millennia.
