Bear Glacier - Kenai Fjords National Park, Alaska

The stripes you see running down the center of this glacier are called “medial moraines.” This means the glacier is made up of more than one flow of ice. On Bear glacier two flows of ice come together and where their lateral moraines meet, the large medial moraine is formed.
