Last Wednesday night we hiked out to Hut Point, then on to the Sea Ice to visit the Observation Tube. It's a long metal cylinder that's suspended down a large hole drilled into the ice. You descend down the tube onto a viewing platform to see the ocean floor and up to the bottom of the ice.
It's a snug fit. Dave's the first one down.

Here's a shot of Dave way down there.
