The explorer Captain
George Vancouverfound Icy Strait, at the south end of Glacier Bay, choked with ice in 1794. Glacier Bay itself was almost entirely iced over. In 1879 naturalist John Muirfound that the ice had retreated almost all the way up the bay. By 1916 Grand Pacific Glacierwas at the head of Tarr Inlet, about 100 km (65 miles) from Glacier Bay's mouth. This is the fastest documented glacial retreat ever. Scientists are hoping to learn how glacial activity relates to climate changes from the retreat.
Plants progressively moved in as the glacier retreated, so a 200-year-old
spruceand hemlock forest presently exists at the entrance, grading up to more primitive plants such as mosses and lichens at the head of the bay. Because of current local climate change due to global warming,Fact|date=August 2008 some glaciers are now retreating at a rate of up to a quarter of a mile per year.
Glacier Bay contains sixteen
glaciers, twelve of which reach shorelines and calve (shed broken pieces of ice) to produce icebergs.
