We went in at Scab Creek 2 days after the storm. Based at Dream L. Day hike past Rainbow L to the pass, so in between Europe Canyon and Bonneville. We had to crawl over or around several trees on the way in. Nothing like what we did at Big Sandy the day before (we were the first to go in). There was no issue at Rainbow, though we took the West side of the lake.

It's probably no worse accessing Bonneville or Europe starting from Scab Ck now, even if they haven't done any clearing. Cooks has more trees so may be different. You can easily access Wall by going in at Island and using the off trail route even if the route up Pole Ck is blocked. I'd be surprised if it's not accessible from Pole Ck trail. Too many outfitters use it to Cook Lakes. They may detour via Monument Ck and have cleared a path that way. Great Outdoor Shop would be a good source of updated info.
