Climbed with TacoDelRio. We were treated to 2000 vertical feet of consolidated snow in late May. The approach is a little nasty, but it keeps the crowds away. I assume that this route has been done before, but I haven't heard of a prior ascent.
Did this today with Patrick (Lilbitmo). Awesome route! Just over 5 hrs up and 3 hrs down. We descended the same way we came up and were treated to a 2,000' glissade. All the snow bridges were suspect and required extra care--especially in the afternoon.
