1988 Map of Pinnacle Lake

About this map

Clear Lake Reservoir dominates the northern reaches of this High Desert landscape, serving as a focal point for the Clear Lake National Wildlife Refuge in northeastern California. This late 1980s survey illustrates a region where water management and conservation boundaries intersect. South of the reservoir, the Modoc National Forest encompasses a terrain defined by seasonal water bodies and drainage systems. The map traces the paths of Mowitz Creek and Boles Creek as they navigate the volcanic plateau. Smaller features like Red Lake and Pinnacle Lake provide critical reference points within the forest's expansive grid. The presence of established township lines such as t47n t46n and r7e r8e highlights the systematic land division used for resource management in this corner of the state.
