The glacier twists its way through western Alaska's Chugach Mountains.

The bald streak at the bottom of the mountains, called the trimline, shows this glacier has lost 1,300 feet (400 m) of thickness.

[citation needed] The glacier's speed of retreat at the terminus reached a maximum of nearly 30 meters (98 ft) per day in 2001, when it was discharging icebergs at approximately 7 cubic kilometers (1.7 cu mi) per year; the glacier has subsequently slowed down, resulting in an increase in retreat rate.

The retreat has been accompanied by nearly 500 m (1,600 ft) of thinning at the present position of the terminus.

In the next few decades it is expected to retreat another 15 km (9.3 mi), to a point where the bed of the glacier rises above sea level.
