We were shocked after parking the car at the end of the gravel to only have to march about 300 yards or less around a bend to reach the trailhead. On return the next day, we could have made it another 100 feet or so. I would say the trail is 98% covered still. The first mile has a few bare spots, but that's about it.
We took the Colchuck Glacier route. I wore my helmet after listening to all kinds of stuff come off of Dragontail the evening prior. Turns out it really wasn't necessary, but it was hard to tell where the debris path was in the col.
It was an amazing climb with a beautiful approach.
