Glacier Bay National Park preserves the wilderness on either side of a major coastal waterway on Alaska Sound. Many glaciers flow into the bay, providing both a living laboratory of glacial geology and dramatic, exciting scenery for the visitor. Most people see Glacier Bay from the deck of a cruise ship or ferry. Some offer excursions to the glaciers for the adventuresome.
Prominent glaciers within the national park include Reid Glacier,
Margerie Glacier,
Johns Hopkins Glacier,
and Grand Pacific Glacier,
an excellent example of a receding glacier..
