About this map

The high volcanic plateau of the California-Oregon borderlands is defined here by the rugged cinder cones and basaltic flows of the Lava Beds National Monument. This 2015 survey illustrates the geologic complexity of the Modoc National Forest, where prominent features like Caldwell Butte, Cougar Butte, and the Three Sisters rise above the surrounding terrain. The map details the transition between Siskiyou and Modoc counties, following the Monument road through a landscape shaped by ancient eruptive activity.

A network of forestry and fire access roads, such as the Pumice System Spur and Tichnor Cave road, provides a modern perspective on land management in this protected wilderness. Significant landmarks including Captain Jacks Bridge and the Gravel Pit Two site offer a look at how this volcanic environment has been navigated and utilized. From the heights of Big Sand Butte to the volcanic formations of East Sand Butte, the map records the enduring character of this high-desert environment.
