For me these are one of the mountain groups that are great to get to for even two or three days. In reach of Seattle the mountains have some great endemics - some you know - such as Campanula piperi and some such as Viola flettii which are very pretty but I hadn't come across at all.

These pics are of Ruby Beach on the Pacific coast with the mass of driftwood on the beach, of the cold rainforest at Hoh Valley and of the endemic Olympic marmot (Marmota olympus if you can believe it) near Hurricane Ridge.

I'll post some plant pics in a follow-up.
