2012 Map of Mount Henry

About this map

Mount Henry stands as a central peak in this high-altitude landscape within the Sierra Nevada, where the S Fork San Joaquin River carves through deep canyons and meadows. The map documents a complex glacial topography defined by the Glacier Divide and the presence of the Matthes Glaciers near the eastern boundary. This 2012 survey illustrates the hydrological network feeding the river, including the Devils Punchbowl and a high density of alpine basins like the Red Mountain Basin. Significant transit corridors through this wilderness are marked by Hell for Sure Pass and Mosquito Pass, which navigate the steep elevations between Piute Canyon and the Le Conte Divide. Named landmarks such as John Muir Rock near Aspen Meadow and the expansive Evolution Valley reflect the era’s established nomenclature for this protected backcountry region.
