CJO, Tracy Arm Fjord is beautiful, but it is not a glacier, it was about 800 years ago. Here is a picture of it from a year ago:
I highly recommend the helicopter/dogsled tour. It is an amazing tour and worth every penny. As I mentioned in another post in the Alaska thread, we did the ERA helicopter/dogsled tour. Unlike other dogsled tours, this one you actually get to ride on a dogsled for about 45 minutes on top of a glacier. It was the most memorable tour I have ever taken.
