The Modoc Line Rail Trail winds through this high-elevation landscape, tracing a historic transportation corridor that once connected the remote corners of the region. Crossing the boundary between Modoc and Lassen counties, the map highlights the transition from the irrigated ranchlands along the South Fork Pit River to the timbered slopes of the Modoc National Forest. This 2018 survey reveals a terrain defined by significant water management features, including the expansive West Valley Reservoir and Smith Reservoir, which serve as vital resources in this arid environment.
