Eylar Mountain towers over a complex landscape of deep canyons and seasonal drainages in this 2012 study of the California Coast Ranges. The map documents a network of rural outposts and family landholdings, including Parman Ranch, Fisher Homestead, and Camp Bessie, which highlight the area's history of ranching and remote habitation. Water sources are critical features of this terrain, with McGlinchey Spring and Banta Spring providing life-sustaining points among the arid ridges. Drainage patterns are defined by the winding paths of Arroyo Valle, Arroyo Mocho, and Arroyo Bayo, which have carved significant landmarks like The Narrows. This modern survey also preserves the names of early industrial and agricultural sites such as Coffey Mill Gulch and Sherman Flats, offering researchers a clear view of how these interior valleys were utilized before contemporary conservation and land management efforts shaped the region.
