History
Joseph Whidbey, master of the Discovery during George Vancouver's 1791-95 expedition, found Icy Strait, at the south end of Glacier Bay, choked with ice in 1794. Glacier Bay itself was almost entirely covered by one large tidewater glacier. In 1879 naturalist John Muir found that the ice had retreated almost all the way up the bay, a distance of around 48 miles (77 km). By 1916 the Grand Pacific Glacier was at the head of Tarr Inlet about 65 miles (105 km) from Glacier Bay's mouth. This is the fastest glacier retreat ever documented. That said, not all of park's glaciers are in retreat. Scientists working in the park and preserve hope to learn how glacial activity relates to climate change.

Famous quotes containing the word history:
“What is most interesting and valuable in it, however, is not the materials for the history of Pontiac, or Braddock, or the Northwest, which it furnishes; not the annals of the country, but the natural facts, or perennials, which are ever without date. When out of history the truth shall be extracted, it will have shed its dates like withered leaves.”
—Henry David Thoreau (1817–1862)
“So in accepting the leading of the sentiments, it is not what we believe concerning the immortality of the soul, or the like, but the universal impulse to believe, that is the material circumstance, and is the principal fact in this history of the globe.”
—Ralph Waldo Emerson (1803–1882)
“The second day of July 1776, will be the most memorable epoch in the history of America. I am apt to believe that it will be celebrated by succeeding generations as the great anniversary festival. It ought to be commemorated, as the day of deliverance, by solemn acts of devotion to God Almighty. It ought to be solemnized with pomp and parade, with shows, games, sports, guns, bells, bonfires and illuminations, from one end of this continent to the other, from this time forward forever more”
—John Adams (1735–1826)
