The San Joaquin River carves through the heart of the Sierra National Forest in this early 20th-century topographic record. The map documents an era of industrial expansion into the high country, evidenced by the early infrastructure of Power House No. 1 and Power House No. 2 near Big Creek Canyon. Timber and mining operations are scattered throughout the slopes, including the Peckinpah Mill, Moore Mill, and Providence Mine.
