2020 Map of Big Hole

About this map

Big Hole, a massive maar crater, dominates this volcanic landscape along the border of Klamath and Lake Counties. This 2020 survey illustrates the meeting point of the Deschutes National Forest and the Fremont National Forest, where high-altitude forestry management defines the terrain. The central crater is flanked by Big Hole Butte, while other volcanic features like Hooligan Hill and Mowich Spring Butte punctuate the surrounding forested plateaus. The map details the complex network of forest service roads and section lines within Township 24 South, Range 11 East and adjacent ranges, showing how modern resource management and geographic boundaries intersect in this unique geological basin.
