Lassen National Forest and Modoc National Forest converge in this high-altitude landscape of Lassen County, where the Pit River carves through the volcanic terrain. The small community of Little Valley serves as a focal point near the southern boundary, connected by a network of forest and logging routes such as Little Valley Rd and Black Gulch Rd. The topography is defined by a series of prominent peaks including First Butte, Second Butte, and Third Butte, which rise out of the Big Valley Mountains. Water management is evident through features like Spring Gulch Reservoir and Loomis Reservoir, essential for the region's ranching and forestry history. The map also traces several canyons and gulches, such as Deadhorse Canyon and Blacks Gulch, illustrating the complex drainage patterns of the Clarks Valley area.
