About this map

The N Fork Kings River carves a deep path through this section of the Sierra National Forest, defining the high-altitude topography of Fresno County. The landscape is characterized by its technical water management infrastructure, including the Black Rock Reservoir and a series of underground conduits such as the Balch Tunnel and Haas Tunnel. These engineering works support the hydroelectric operations centered around Balch Camp, a small settlement established to maintain the power facilities in this remote canyon environment.

Away from the river, the terrain rises toward Patterson Mtn and the striking Patterson Bluffs, where a network of forest roads like Mc Kinley Grove Rd and Ross Crossing Rd provide access to seasonal sites. Names like Sawmill Flat, Cabin Meadow, and Bear Wallow reflect the area's history of timber harvesting and traditional mountain use, while prominent features like Indian Rock and Poison Ridge serve as important landmarks for navigation through the high-elevation forest.
