About this map

Ishi Caves (Yahi Indian Camp) serves as a primary cultural focal point in this portion of Tehama County, situated within the Ishi Wilderness and the Ishi State Game Refuge. The landscape is defined by the drainages of Mill Creek and Deer Creek, which have carved deep canyons through the Graham Pinery and various flats like Digger Pine Flat and Deer Creek Flat. This area preserves a legacy of remote seasonal habitations, indicated by numerous camps such as Apperson Cow Camp, Leininger Camp, and Skeleton Camp, which likely served ranching or hunting purposes in the late 20th century. Local landmarks like Moak Cave and Sulphur Lick further characterize the geologic and pastoral nature of the terrain. The presence of Grapevine Crossing and Deer Creek Crossing highlights the historical importance of established fords for traversing the canyon-cut highlands of the Lassen National Forest.
