We spent the day floating around the Hubbard Glacier dodging ice cubes and ice bergs. It is said you can only see 10% above the water. We viewed the glacier from our room until the Captain left the area so other ships could advance. It was clear but 35 degrees outside, so it was cold! Our time at the glacier was from 1-4 although we stayed a little longer to watch the small calving which was occurring. It was very interesting. Hope the pictures tell the story except you can't see the calving unless the pixs are enlarged.
