Mendocino National Forest encompasses the majority of this terrain along the Lake County and Colusa County boundary. The landscape is defined by a dense network of ridges and water sources, including Potato Hill and the prominent Blue Slides Ridge. For those interested in historical water use and geothermal activity, the map identifies Crabtree Hot Springs situated along the Rice Fork. The presence of numerous named springs such as Madrone Spring, Kneebone Spring, and Rabbit Glade Spring indicates the critical importance of water access in this high-elevation backcountry. Settlement evidence is sparse, represented by specialized locations like Board Camp Ridge and the Upper Lake-Clearlake Oaks Division boundary. The topography is also dotted with glades, such as Mauser Glade and North Glade, which provide a distinct contrast to the surrounding forested ridges like French Ridge and Hale Ridge.
