2021 Map of Little Mud Flat

About this map

Secret Valley and the northern slopes of the Skedaddle Mountains define this high-desert region of Lassen County. The landscape is characterized by a network of water management features essential for ranching and survival in the arid Great Basin transition, including Chalk Bluff Reservoir, Lava Rock Reservoir, and Horsecamp Reservoir. To the southwest, the terrain descends toward the Honey Lake Valley, while isolated water sources like Brubeck Spring and Laver Spring dot the more mountainous southern sections. The map traces the routes of Old Humboldt Rd and Smoke Creek Ranch Rd, providing a record of the remote transportation corridors that connect these high valleys and mountain ranges. This survey documents the intersection of natural geological formations and the human-made infrastructure required to sustain the cattle and ranching economy of the early 21st century.
