2018 Map of Pinnacle Lake

About this map

Clear Lake National Wildlife Refuge dominates the northern reaches of this landscape, preserving the marshy fringes and waters of the Clear Lake Reservoir. This high-desert terrain in Modoc County is characterized by seasonal water systems and volcanic landforms, where Mowitz Creek drains toward the central flats. The transition from protected wetlands to the Modoc National Forest in the east reveals a remote environment marked by scattered water features such as Red Lake and Pinnacle Lake. Distinctive topographic landmarks like The U and Bump Heads serve as natural navigational aids in a region defined by its isolation. Local hydrologic history is reflected in names like Negro Bend Spring and Barry Tank, indicating the importance of reliable water sources for both wildlife and land management in the northeastern corner of California.
