Margerie Glacier

Margerie Glacier ends at the sea at the northern reach of Tarr Inlet, the farthest point of the Glacier Bay waterway. It is about 21 miles long, starting in the Fairweather Range above 9,000 feet, and flows about 2,000 feet a year (roughly 6 feet a day). It rests on an underwater ledge, so ice calves into the fjord as icebergs that harbor seals, sea otters and kittiwakes use. The terminus was long stable, but since 1998 its northern third has receded, and by 2017 deep embayments had formed and bedrock was exposed.
