Our goal in Whittier was to take a 10 hour cruise around Prince William Sound. We canceled it the first day because of rough weather, but got to take it the following day. There was so much fog at the beginning of the trip that the captain had to beach the boat on this island. We couldn't see more than 5 feet in front of us and could hear fog horns echoing throughout the Sound. We waited about 30 minutes before heading back out.
