This was yesterday along the West Rim Trail a mile and a half past Angel’s Landing at about 6,500 feet. This elevation is at peak right now! Much of this trail is above 7,500 feet, and those colors are past, and most on the ground. In the valley floor, colors are just beginning to change. I would say at the Temple of Sinawava, maybe 20% of the leaves are now yellow, with a bit less further down the valley. The next few weeks should be great.
