We hear the sound of dripping water, an image of water appears, and then more text tells us how a retreating glacier formed the Hudson River valley at the end of the last ice age.
Visitors will be able to learn, for instance, how the Wisconsin glacier formed kettle ponds, where hikers might spot an opossum or Eastern chipmunk, how to tell the difference between a white snake root plant and a spice bush and where to find the Tibetan Museum and the wooden carousel in Willowbrook Park.
The outflow of the glacier forms the headwaters of the Illecillewaet River.
In spite of the dome growth next to it, a new glacier formed rapidly inside the crater.
The glacier formed after the 1980 Eruption and due to its location, the body of ice grew rapidly, unknown to the public for nearly 20 years.
That name has been in wide use with the public (at least those who were aware of the glacier's existence) for the two decades since the glacier formed, and has appeared in several scientific publications too.
Immediately to the south, the bay terminates at the Drygalski Ice Tongue, a gigantic, floating glacier, formed where the East Antarctic Ice Sheet pours through a low stretch of the mountains.
A massive central lava dome emplaced from 1980 to 1987 occupies the center of the crater, and the glacier formed in the shape of a horseshoe around the dome, with two terminal moraines on the eastern and western sides.
The Fairweather Range of hills which feeds the John Hopkins and Margerie Glaciers form the western boundary of the Glacier Bay and the highest mountains seen here are the Mt. Fairweather (15300 feet), Mt. Quincy Adams (13650 feet), Mt. Salisbury (12000 feet), Mt. Crillon (12276 feet), Mt. Bertha (10204 feet), Mt. Abbe (8750 feet) and Mt. Cooper (6780 feet).
The Himalayan-Hindu Kush mountain glaciers form the water towers of Asia.
