Hubbard is one of the few glaciers in Alaska that is advancing - in fact, it's been advancing about 75 feet a year since 1895 when people first started taking note of it. What that means for visitors is that this is one of the glaciers where you are most likely to see calving (where chunks of the glacier fall into the sea). Sometimes the icebergs created block ships from getting close to the face of the glacier.
