About this map

Mining operations and remote homesteads define this rugged corner of the Diablo Range where San Benito, Monterey, and Fresno counties meet. The landscape is heavily marked by the region's mercury and asbestos extraction history, featuring notable sites such as the Alpine Mine, St Thomas Mine, and the San Benito Mill Site near the headwaters of the San Benito River. A network of jeep trails and historic routes like the Sawmill Trail connect these industrial outposts to small settlements and camps like Lewis Flat and Roach.

Natural landmarks and water sources are critical in this arid environment, evidenced by the numerous named springs including Poison Spring, Fawn Spring, and Willow Spring. Prominent peaks like San Benito Mountain and The Picachos overlook deep drainages such as Los Gatos Canyon and Nimrod Canyon. The inclusion of a lone Grave in the southern portion of the map provides a poignant detail for genealogists researching the families who once worked the claims along Clear Creek.
