About this map

Lassen National Forest terrain dominates this topographical study, where the historic Humboldt Road cuts across the landscape near the Tehama Co Plumas Co border. The map focuses on high-altitude ranching and drainage systems, particularly within the namesake Humbug Valley and the expansive Soldier Meadows. These open meadowlands are fed by a network of waterways including Soldier Creek and Butt Creek, supporting early regional holdings like Baccala Ranch and Lemm Ranch.

Recreational and transit routes are prominently featured, with the Pacific Crest National Scenic Trail winding through the west along Ruffa Ridge. The presence of a Quarry and various campgrounds suggests a landscape balancing natural resource extraction with the burgeoning seasonal tourism of the late twentieth century. Significant topographical markers like Middle Hollow and Big Springs help define the drainage patterns of the Little Grizzly Valley area.
