About this map

The boundary between Alameda Co and Santa Clara Co cuts through this high-elevation backcountry, centered on the prominent peak of Eylar Mtn. The landscape is defined by a series of high ridges, including Beartrap Ridge and Packard Ridge, which separate deep drainages such as Arroyo Mocho and Arroyo Valle. Historically, this area served as a remote outpost for seasonal camps and mountain activities, evidenced by locations like Mowry Camp, Colorado Camp, and Camp Bessie.

Transport is limited to a network of primitive routes and a Jeep Trail, reflecting the isolation of the Burnt Hills. Small, family-named sites like Graves and a solitary Prospect indicate the sparse human footprint in this mountainous terrain. The map also highlights natural landmarks such as The Narrows and numerous seasonal water sources like Hoodoo Spring and Banta Spring, which were vital for those traversing these steep canyons.
