About this map

Clear Lake Reservoir dominates this high-plateau landscape along the Oregon California State Line, where the Lost River winds through the northern reaches of the Modoc National Forest. The map documents a sparsely populated ranching territory characterized by family-named holdings such as Holbrook Ranch, Chandler Ranch, and the McNeil Ranch. A historical layer is visible through the path of the Emigrant Trail, which traverses the terrain north of the reservoir near Fiddlers Green.

The southern portion of the sheet is defined by prominent volcanic features, including Double Head Mtn and Carr Butte, which overlook the expansive Clear Lake National Wildlife Refuge. The presence of numerous water sources like Mammoth Sprs, Negro Bend Spring, and Rimrock Spr suggests the critical importance of water management in this arid region, underscored by the Gaging Station and various reservoirs like Willow Valley Res tucked into the surrounding valleys.
