1981 Map of Clio

The high country of the Plumas National Forest and Tahoe National Forest is dotted with evidence of earlier resource extraction, including the Hayden Mine, Hayes Mine, and Woodchuck Mine. Topographical landmarks like Mills Pk Lookout and the Pacific Crest National Scenic Trail near Haskell Peak indicate the region's importance for both forest management and recreation. The map meticulously records family-named landmarks like Mohawk Valley Ranch and the meadows and saddles that defined travel through these passes.
