As many of you may know, kings canyon was carved by glaciers into its u-shape, which is clearly seen from canyon view pullout in cedar grove. these glaciers were about 1,600 feet (488 meters) deep! to help put the immense size and depth of these glaciers into perspective, take a look at north dome next time you're at zumwalt meadow. about halfway up the cliff face, you'll be able to see horizontal scratches - those were created as the glacier slid past!
