Mark climbing an ice wall on the Glacier.

This was the coolest thing. I saw contestants on the Amazing Race do this and thought: "How hard can that be?"

Hard. Your toes definitely get a workout. All the while you are surrounded by this amazing scenery from the glacier.

The idea is to use your legs. The ice picks are only for stabilization. The goal is to pound the toe of your foot into the ice wall, step up on that foot, and pound the toe of your other foot.

You can tell that is Mark from the large rear end.

Look Mom, one hand and one foot! Crazeee!
