Looked for fall and found winter! Found the bootpath from the ranger cabin. Was told it was a total walkup but I ran into a short exposed scramble at the end. Made it to the summit and was granted excellent views.
Couldn't find a way around the steep, lingering snowfields on the N side of the E ridge. Ended up dropping down over Knapsack Pass and hiking up and thru Spray Park before returning to Mowich Lake.
