Walking on the Glacier

I am not sure how I thought glaciers ended, but I think I imagined a wall of ice. In some parts of this terminus of the glacier, there are cliffs of ice. Here along this edge of the glacier, the people are standing on the ablation moraine, which is mostly still ice from the glacier. The pile of debris along the side is a lateral moraine composed of glacial till. The water coming from the left in the photo is a subglacial stream. Where I was standing to take this photo was solid ice covered with a thin deposit of till.
