Here's an explanation, from geology.com, of the "V" formation short-shrifted at the top:
Hanging Valleys and Waterfalls 'During the time of maximum glacial advance, a large trunk glacier filled Yosemite Valley. Smaller tributary glaciers flowed down adjacent valleys and merged into the trunk. When the glaciers retreated, the trunk glacier had cut a much deeper valley than the tributary glaciers, forming hanging valleys where the tributary glaciers joined the trunk. Today waterfalls such as Yosemite Falls and Bridalveil Falls mark the mouths of these hanging valleys.' |
This was taken from the bus window as we were pulling away from Yosemite Lodge
on our way to all the sights, and it was one of two shots I got.
