Grenville Channel is a long narrow channel between high mountains between Pitt Island and mainland British Columbia. It is part of the inside passage to Alaska. It is probably named after Sir Richard Grenville, an ancestor of Captain George Vancouver who charted a lot of this area. In this image the BC Ferries ship Northern Expedition can be seen moving through the channel on its way north in early morning light, diminished by the size of the mountains.
This is stunning Terry! It's amazing in B/W - I still think about our trip to Alaska and how much fun we had. The moment I saw this photo, and before I read your comments, I thought "Alaska?" Beautiful!
