About this map

Jess Valley dominates this high-altitude landscape in the northeast corner of California, where agriculture and federal land management meet. The valley floor is defined by an intricate network of irrigation features, including a prominent ditch system that supports the Blue Lake Ranch. These water diversions flow from the South Fork Pit River and Mill Creek, illustrating how mid-century ranching operations adapted to this remote mountain basin.

Bordering the valley to the east and south is a transition into the Modoc National Forest, featuring the South Warner Wilderness and Mahogany Ridge. Recreation and administrative presence are evident through the Little Meadows Campground and a Guard Station near Blue Lake. The presence of numerous named water sources like Parsnip Springs and West Valley Spring suggests a reliance on scattered perennial water for both livestock and forest service operations.
