About this map

The high Sierra Nevada crest dominates this topographical study, defined by the jagged boundary where the Inyo National Forest meets the Sierra National Forest. Centered on the massive peak of Mt Abbot, the landscape is a complex of glacial cirques and high-altitude basins. The drainage systems of Mono Cr and Hopkins Cr carve through the granite, connecting a high-density network of alpine water bodies including Upper Hopkins Lakes, Ruby Lake, and the expansive Pioneer Basin.

Transit through this vertical environment is limited to historic pack routes such as the Mono Pass Trl and Hopkins Pass Trl, which navigate the steep divides between watersheds. The map documents the intricate recession of the landscape into named glaciated canyons like First Recess, Second Recess, and Third Recess. These features, along with prominent landmarks like Mono Rock and Recess Peak, illustrate the geological character of the high country before the modern era of climate shift significantly altered these perennial snowfields and lakes.
