USGS Topo · Published 2012About this map
Ambrose Valley and the surrounding Lassen County uplands are defined by a network of seasonal water sources and steep drainages. Named family locations such as Dan Ryan Place and Scotty Place suggest a history of localized settlement and ranching in a landscape where water is the most critical resource. These sites are linked by rugged thoroughfares like Ash Valley Rd and Ash Creek Campground Rd, which provides access to the Ash Creek Campground.
