2012 Map of Tumey Hills

About this map

The Tumey Hills and Griswold Hills define this arid landscape in Fresno County, where the relief is carved by seasonal drainages such as Panoche Cr and Silver Cr. This 2012 survey shows the persistent influence of the petroleum industry on the local geography, specifically within the Vallecitos Oil Field near the southern boundary. The topography is marked by distinctive features like Right Angle Canyon, where the sharp turns in the drainage patterns reveal the structural geology of the region. Access through these highlands is primarily facilitated by Panoche Rd, which meanders across the hills to connect the western and eastern slopes. The map reflects a modern record of a sparsely populated resource landscape, characterized by winding 4WD trails and a lack of permanent settlements.
