Clear Lake National Wildlife Refuge dominates the northeastern quadrant of this landscape, encompassing the extensive waters and marshlands of the Clear Lake Reservoir. The terrain to the west and south is defined by the high, volcanic elevations of the Modoc National Forest, where the prominent peak of Double Head Mtn rises above a series of high-desert lakes and drainages. The mapping reveals a sparse, high-altitude wilderness characterized by geographic landmarks like the Clear Lake Hills and unique features such as Bird Island and The U. A notable specialized facility, Oth Radar, is located in the southern reaches of the quadrangle, reflecting modern infrastructure within this remote territory. The presence of numerous small water bodies, including Pinnacle Lake and Double Head Lake, highlights the complex hydrology of this high Modoc County plateau.
