Arm Fjord, South Sawyer Glacier, Alaska. The prominant dark-light
line in the rock above the boat marks the glacial ice height
in 1992. At that time, the ice extended to about 1 mile to
the right of this point. Today, as a result of warmer temperatures,
the ice limit is further inland, about 0.5 miles to the left.
