1997 Map of Four Corners Rock

About this map

Bolly Ridge and Jones Ridge dominate this high-elevation landscape where the Six Rivers National Forest meets the Mendocino National Forest. At the time of this late-twentieth-century revision, the area remained a strictly managed wilderness, protected as the Yolla Bolly-Middle Eel Wilderness. Within this complex terrain, isolated points of human activity are documented, including the Travis Ranch and Vann Cabin, which provide evidence of the region's ranching and seasonal history. The drainage network is clearly defined by the Mad River and the Middle Fork Eel River, while localized industrial history is noted at the Trout Creek Mine (Site) and Blue Jay Mine (Site). Landmarks such as Four Corners Rock and Big Butte serve as primary navigational points in a terrain defined by steep ridges and secluded basins like Clarks Basin.
