Toured up to mt Grant via tunnel crk. Large D3.5 or so sized slide down main gut with 20+ foot piles that was covered by last weeks snow. Ran from below glacier to meadow/headwaters of creek. 5-10 foot chunks and flanks that gouged high walls on both sides and “groomed” a couple hundred feet of flats. New snow was a foot or so that bonded well to old stuff.
