Glacier Bay, a water inlet 65 miles long, is a long way from modern civilization, and a place of spectacular beauty.
The ship spent a few hours at the Margerie and Grand Pacific glaciers. These rivers of ice have different appearances.
Cutting through more granite, the Margerie glacier has a whiter appearance, but picks up debris at the margins.
The Grand Pacific glacier goes through softer rock formations, picking up lots of rocks and dirt, like the muddy Mississppi River...except a lot colder and way slower, but still looks dirty.
