On the way to the glacier, we had to pass to the outside of a restricted area (marked by buoys and their resident sea lions) for the terminus of the Alaskan Pipeline. The terminus is in the background of this photo. Boats are not allowed inside the buoys, and tours were discontinued after 9/11 so this is the closest tourists can get:
On our trip we got lucky -- the normal iceberg barrier was gone, so we were able to get very close to the glacier, within .8 mile. Even the crew was excited -- they told us only about 100 people had ever gotten that close to it!

When two glaciers come together, as they do here, lateral moraines meet in the middle and this accumulation of dirt and rocks is called a medial moraine.
