The San Joaquin River carves through this portion of the Sierra National Forest, marking the boundary between Madera and Fresno counties. This early 1980s landscape is defined by its hydroelectric infrastructure, with a series of facilities including Powerhouse 2, Powerhouse 3, and Powerhouse 4 connected by an aqueduct and surge chambers. The impounded waters of Redinger Lake dominate the canyon floor, providing a recreational focal point with its boat ramp and access via the winding Italian Bar Road.
