About this map

Alta Sierra and the surrounding heights of the Sequoia National Forest define this 1970s landscape, where alpine recreation and historical resource extraction meet. The terrain is marked by a legacy of early industry, evidenced by the Old Likely Mill (Site) and Browns Mill (Site), as well as the Keyes Mine near the settlement of Keyesville in the southeast. These sites point to a rugged economic history of timber and mining that predates the modern development of Shirley Meadows and its Ski Lifts.

Administrative and recreational footprints are prominent, from the Summit Forest Service Station at Greenhorn Summit to various mountain camps like Camp Kaweah and Yenis Hante. The map tracks a network of forest roads, including Rancheria Road and Sawmill Road, which navigate the drainages of Cedar Creek and Tillie Creek. The transition from historical work sites to seasonal mountain retreats is captured here in detail, preserved just as the region’s character was being solidified for the late 20th century.
