After I posted the story found below on this page, I remembered that I took a photo illustrating this situation when I climbed Vogelsang Peak just two days ago.
Drainage below McClure Peak (near Mt. Lyell) in Yosemite. Photograph from the summit of Vogelsang Peak, October 11, 2003.
Look in the shaded portion of the ridgeline at the far right side of the picture - directly above the rightmost lake - where you can spot two small, shaded permanent snowfields. Look down the slope below them to see older terminal moraines marking the previous extent of the glaciers.
Sierra devotees may recognize the following peaks, from left to right: Parsons Peak, Mt. Simmons, Mts. McClure and Lyell.
(Note: I am aware that many factors can contribute to the natural increase and decrease in the size of glaciers.)
