1993 Map of Mt. Williamson

About this map

Mt Williamson dominates the center of this high-altitude survey, marking a formidable point on the boundary where Inyo National Forest meets the wild upper reaches of Sequoia National Park. The landscape is a network of granite peaks and alpine basins, including the Williamson Bowl and Lake Helen of Troy. This 1993 provisional update focuses on the complex drainage systems of the Eastern Sierra, such as Shepherd Creek and Bairs Creek, which descend sharply toward the Owens Valley. High-mountain passage is documented via the John Muir Trail and the steep Shepherd Pass Trail, which reaches Shepherd Pass at the park line. Small human imprints in this wilderness environment are limited to remote sites like Anvil Camp and the Corral Gaging Station, used for monitoring the vital water runoff from the snowpack. The presence of the California Bighorn Sheep Zoological Area underscores the region's importance as a protected wildlife corridor during the late twentieth century.
