Frozen River and Glacier.


Like a frozen river, a glacier flows slowly through a rocky landscape shattered by ice. Line of rocky debris build upon its surface as it gouges out a deep valley.


Where a glacier meets the sea, there is a constant battle between ice and water. Sometimes avalanches of ice break off and crash into the sea, as has happened with this glacier in Alaska, US.
