Jess Valley and the surrounding high-altitude terrain of Modoc County define this landscape, where the S Fork Pit River flows through a series of meadows and canyons. The settlement of Campbell and nearby Flourney occupy the northern reaches of the valley, while the Modoc Peatmoss Company indicates a specific local industrial use of the valley's wetlands. To the south, the topography rises toward Mahogany Ridge, and the drainage basin becomes more complex with numerous seasonal and perennial flows like Harvey Creek and Parsnip Creek.
