About this map

Peachtree Valley and the Diablo Range define this high-country landscape along the border of Fresno and Monterey counties. In the northern reaches, Peachtree Rd follows the valley floor, connecting the drainage of San Lorenzo Cr with the surrounding canyons. The terrain is deeply incised by complex water systems, including Pancho Rico Cr and Sargent Cr, which have carved out notable landmarks like Little Bitterwater Canyon and Sargent Canyon.

The southern portion of the map is dominated by a series of parallel valleys and canyons, most notably Indian Valley and Medford Valley. Natural springs are a persistent feature of this arid environment, with locations such as Brock Springs, Ebien Spring, and Powell Spring scattered across the township lines. Remote access is provided by unpaved tracks like Indian Valley Rd and Smith Mountain Lookout Rd, reflecting a landscape primarily shaped by cattle ranching and watershed management in the early 21st century.
