Wowee! Night whales! Whales, but at night! Like, in darkness.
Most whale watching happens during the day, when you can see them. I was pretty happy that after dinner, near sunset (the above photo was taken at 9:30 PM,) we found more whales. Two humpbacks, doing some leisurely feeding at the surface, ignored the ship as we idled to watch them.
The water was calm enough that as the whales came to the surface to breathe, we could hear each breath clearly. Alaska has these great passages between islands that are deep and wide enough to hold significant amounts of food for whales, and are protected from the open ocean enough that they provide an excellently flat surface for viewing.
