2012 Map of Pinnacle Lake

About this map

Clear Lake Reservoir dominates the high desert landscape of Modoc County in this 2012 survey, revealing a drainage system defined by intermittent water sources and seasonal basins. The hydrology of the region is anchored by the reservoir and several smaller catchments, including Red Lake and its eponymous namesake Pinnacle Lake to the south. The mapping of Mowitz Cr and isolated features like Negro Bend Spring and Barry Tank suggests a reliance on specific, scattered water points in an otherwise arid environment. Evidence of human movement through this northern California backcountry is primarily represented by Clear Lake Reservoir Rd, while distinctive natural formations like Bump Heads and the landform known as The U provide essential navigation markers for those traversing the Modoc Plateau.
