It has been almost three weeks since I was up near the base of Muir. There was plenty of snow above ~9000ft. It was pretty soft in all of the areas that we got on it and never considered pulling crampons out of our packs. Muir's East face was bare and dry. Not a lot of info for you, but something is better than nothing, and I figured that snow coverage on the approach is probably what you were most interested in anyways.
