Porteau Cove is a quaint little provincial park here in BC, about 30 minutes drive from my home. It's a great little camping spot, but is perhaps known better as a diver's paradise. The province actually sunk a ship here to create a wildlife habitat and as such it's become a really popular attraction for divers.
I'm not sure what this dock used to service, as there isn't a town here. Perhaps it was to support the logging industry once upon a time.
