Upper mountain is still completely covered (except the usual early exposed band under the rex chairline, anyway,) but most of the lower mountain past chinook is starting to show big holes. You should be able to find paths from top to bottom this weekend, but beyond that will probably require a bit of walking to get all the way to the base.
Green valley is nice and deep though!
Oddly I loved the challenge of trying to make it back to the bottom while the season wore down, each weekend becoming more and more difficult. I remember times when there would be a line about a foot wide at parts and you'd have to point it and keep your speed, and other parts where you had to jump from patch to patch to find a new line.
