That's a good speed. I did it a couple of days later using the Birch Lake route and it was 5 miles and 3 hours longer. And terribly loose (but no snow on the NW chute) so you got the better deal.
Thank you for the note. My route 5 miles shorter? That's a big diffrence. I should write a route description for the East Slope. I didn't realize that the NW climb was such a pain until I saw the chutes with my own eyes. Lucky for me, as nasty as it was to hike between the brush and absolutely no shade the entire day, at least I didn’t have scree.
