1953 Map of Mt Abbot

About this map

Lake Thomas A Edison and the recently flooded basin of the San Joaquin River dominate this mid-century survey of the high central Sierra. The map details a period of hydroelectric development and backcountry recreation, showing the infrastructure of Florence Lake alongside the remote high-altitude routes of the John Muir Trail and Piute Pass Trail. High peaks of the Great Divide, including Mt Abbot and Mt Hilgard, define the watershed between Sierra National Forest and Inyo National Forest. Local history is preserved through small landmarks such as the Pick and Shovel Mine and Fish Camp, while the network of alpine water bodies like Lake Italy and Marie Lake illustrates the complex hydrology of the Sierra Nevada.
