Mariposa Reservoir and its surrounding water management systems anchor this early 1960s study of the foothills where Merced and Mariposa Counties meet. The landscape is defined by the hydrologic network of Bear Creek, Miles Creek, and Owens Creek, each supporting distinct agricultural operations like the Chase Ranch and Cunningham Ranch. An Indefinite Boundary separates the two counties, cutting through a terrain marked by small-scale resource extraction, including several Quarries and the Hills Mine in the northern hills.
