About this map

The Gabilan Range forms the backbone of this landscape, where the jagged boundary between Monterey and San Benito counties follows the high ridgelines. Reaching its peak at Mt Johnson, the terrain is defined by a complex network of steep drainages including Matarana Gulch and Rooster Canyon. These seasonal watercourses flow into larger systems like Willow Creek and the South Fork Willow Creek, shaping a remote geography that has historically limited dense settlement.

Evidence of local ranching and land use is found in the scattered, family-named landmarks such as Ben Graves Canyon, Sullivan Canyon, and Henry Sands Canyon. These names reflect the ancestral homesteads that occupied the high country. In the more level areas, Williamson Valley and Parks Valley provide natural breaks in the topography, while Gloria Lake and the nearby Gloria Valley sit tucked away in the southeastern reaches, accessed by narrow corridors like La Gloria Road.
