Glacier Bay

SSA Photography (17 of 400)

This photograph was taken in Glacier Bay National Park in Southeast Alaska, just west of Juneau.  President Calvin Coolidge proclaimed the area around Glacier Bay a national monument under the Antiquities Act on February 25, 1925. Subsequent to an expansion of the monument by President Jimmy Carter in 1978, the Alaska National Interest Lands Conservation Act enlarged the national monument by 817.2 square miles on December 2, 1980, and created Glacier Bay National Park and Preserve.

This is the Johns Hopkins Glacier, named in 1893 by H.F. Reid after the Johns Hopkins University in Baltimore, Maryland, which sponsored an expedition to this glacier.  It is the only advancing tidewater glacier now (its advance started in 1924 when Grand Pacific Glacier started receding towards Tarr Inlet) and is combined with Gilman Glacier (first got attached to Hopkins in the 1990s, broke off and rejoined several times and once again it appears joined since 2000); both are advancing as one single ice block, and at the waterfront, has a width of 1 mile with a depth of 250 feet, rises to a height of 250 feet and stretches to about 12 miles  upstream.
