Yosemite Falls—A New Perspective
Waterfalls cascading down a valley's walls from far above its floor have long been considered as evidence of a glacial origin for that valley.
Yosemite Falls with their spectacular drop of 2,425 feet (including the Upper Fall, middle cascades, and Lower Fall) are world-renowned and an icon for Yosemite Valley. They are truly unmatched and were recognized as such early on.
Matthes' Wisconsin glacial stage and his mapped morainal complex on Yosemite Creek may include both the Tahoe and Tioga glaciations. If the foregoing diversion scenario for Yosemite Creek is valid, Upper Yosemite Fall, with its “newly” hanging valley, is less than one million years old and may be little more than 130,000 years old. Before its postulated diversion, perhaps little more than 130,000 years ago, Yosemite Creek flowed down an older channel just to the west, from which it cascaded down through the steep ravine that is now the route of the Yosemite Falls Trail
