1990 Map of Ambrose Valley

About this map

Modoc National Forest encompasses the rugged landscape of this northern California terrain, where high-elevation drainage systems and prominent ridges define the local geography. The map captures a complex network of springs, including Pothole Spring, Stump Spring, and Yellow Jacket Spring, which provided essential water sources in this dry mountain environment. The intersection of the Modoc Co Lassen Co boundary splits the territory, while the Ash Creek Trail and Ash Creek Campground indicate the recreational and utility corridors established by the late 1980s. Natural features like Round Valley and Ambrose Valley are framed by substantial uplands such as Deer Spring Ridge and Slate Spring Ridge, illustrating the varied topography of the region. Local nomenclature is preserved through labels like Hunsinger Draw, Messenger Gulch, and Sweagert Flat, offering specific locations for family-named landmarks and historical land use.
