1955 Map of Eylar Mountain

About this map

Coffey Mill and a series of remote camps characterize this high-elevation landscape along the boundary of Alameda Co and Santa Clara Co during the mid-1950s. The terrain is defined by steep ridges like Beartrap Ridge and Valpe Ridge, which drop into deep drainages including Arroyo Mocho and Arroyo Valle. Historically, the area appears largely seasonal or industrial, with labels for Hays Camp, Mowry Camp, and Colorado Camp scattered across the upland flats and gulches. The presence of a Prospect and Tunnels near Camp Bessie suggests localized mining interest in the canyons. Water sources are critical in this environment, marked by numerous named springs such as Banta Spring and McGlinchey Spring. A network of Jeep Trails provides the primary means of traversal through the Burnt Hills and over Packard Ridge.
