Okay, the long story: McMurdo generally relies on an Ice Pier to handle the docking of the various ships that visit our harbor. This past winter, though, the pier didn't freeze enough, and it was declared too unstable to use this season. The decision was made to separate it from the mainland (hence the explosion) and drag it to the end of Hut Point (with the help of our Ice Breaker), where it's out of the way, but where it can be reached this coming winter when crews will attempt to salvage it.
