Glacier Bay National Park in Alaska is a World Heritage Site with 3.3 million acres of spectacular sights and wildlife, including 11 glaciers of which 8 can be seen from the bay. It is a very remote and rugged park as there are no roads that lead to it. The only way to get to Glacier Bay is by either boat or plane. There is only one lodge within the park (Glacier Bay Lodge) and there are no campsites. Campers can stay in the park in almost any area that they want. This past July, we spent almost a full day cruising the bay, taking in it's glaciers. One of the coolest things we saw was this ice cave in the Lamplugh Glacier. The cave was huge, towering about 30 feet at it's highest point, and we had just missed some kayakers that left the cave moments before. The most interesting thing about the cave was that it was temporary. The National Park Forest Ranger told us that it didn't exist several weeks prior to our arrival and that it would likely collapse in the near future.
