Mendocino National Forest defines the rugged divide between Glenn and Lake Counties in this 2018 survey. The landscape is marked by a complex network of named ridges and canyons, including the prominent Felkner Hill and Bowman Ridge. The presence of Ivory Mill Saddle and the associated Ivory Mill Rd suggests a legacy of timber history in this remote section of Northern California. Water resources are primarily found in high-elevation seeps like Jumbo Spring and Hayward Spring, which feed the many creeks cutting through the terrain, such as Clover Cr and Dutch Oven Cr.
