Photo of a glacier located in College Fjord, Alaska. Fjords are long, narrow inlets of sea bordered by steep cliffs. They are created when glaciers cut valleys and later melt. Most fjords are extremely deep, some deeper than nearby seas. The fjord area is home to five tidewater glaciers, which are glaciers that end in water, as well as five valley glaciers and many smaller glaciers. Crevasses are visible on the top of the glacier.
