Lava Beds National Monument dominates the northern landscape of this survey, revealing a complex volcanic terrain marked by features like the Glass Flow and numerous volcanic cones including Caldwell Butte and Cougar Butte. The map captures a critical intersection of Modoc County's history, preserving the site of the Battle of Dry Lake 1873 during the Modoc War. This mid-century view illustrates a region defined by its timber and rail resources, where the Lumber RR and Southern Pacific corridors converge near settlements like Tionesta and Perez.
