2021 Map of Black Rock Mountain

About this map

The Trinity National Forest and Mendocino National Forest converge in this high-altitude landscape defined by the watershed divide between the S Fork Trinity River and the N Fork Middle Fork Eel River. The terrain is marked by a network of named ridges and gulches, including Rainbow Ridge and Mule Gulch, providing a detailed view of the regional topography and forest boundaries. Small named locations like Payne and Penney appear alongside remote landmarks such as Hermit Rock and Tombstone Rock. A complex system of trails and service roads, including the Wild Mad Rd and the Chicago Camp Trl, illustrates the accessibility and management of these public lands. The map also captures specific natural features like Black Rock Lake and the significant Blue Slide formation, offering researchers a clear look at the geological and administrative character of this northern California wilderness.
