The Pit River winds through the northern reaches of this landscape, carving a path past Ostrom Point and Allen Butte within the Modoc National Forest. This 1993 revision, based on earlier aerial photography, captures a high-elevation terrain defined by volcanic peaks and numerous water sources. Notable summits like Black Butte, Iron Mountain, and Fox Mountain anchor the central and southern regions, while the southern edge drops toward the expansive Big Valley.
