Good route and very challenging depending on how much stuff you bring. Fred Becky recommends an ice axe, however there was no need for such in October conditions. The route up the NE shoulder of Whatcom Peak is very exposed, and feels more like class 4 since both hands are required. While the route looks difficult from far, it becomes more reasonable the closer you get. The ridgeline is also exposed but it’s overall very fun scrambling. PLEASE DO NOT follow this route over the Baker River at Imperfect Impasse. The Baker Rive should be crossed above the tallest waterfall. That seems to be the only safe route across the gash that the Baker River makes in the landscape without walking downriver a half mile through brush. Otherwise, this route is decent to follow either direction.
