This is a map of Glacier Bay National Park
Glacier Bay is located in Gustavus, Alaska. There at the National Park
there are many fun and cool things to do there.
How It became a bay and Why
•
The world new very little about Glacier Bay until 1878, when naturalist John
Muir, four Tlingit guides and a Presbyterian missionary came here in a sea canoe.
Navigating with Captain Vancouver's map, Muir discovered the ice had moved
back 40 miles from where Vancouver's survey party saw it just 85 years before.
John Muir was fascinated by the icy wilderness he saw and returned four times
through out his lifetime to study the glaciers and newly uncovered land. Soon,
tourists and scientists began to visit the area. The Bay became a natural
laboratory to learn about the past ice ages, as one could study the moving
glaciers and observe the types of plants and animals that colonize areas after the
glaciers receded.

How the glaciers formed
Ice has been a major land force in the Glacier Bay region for
at least the last seven million years. The glaciers seen in
Glacier Bay today are remnants of a general ice advance the little ice age - that began about 4,000 years ago. True
to its name, this advance in know way to approached the
extant of continental glaciations during Pleistocene times
known as the Wisconsin ice age. The little Ice Age reached
its maximum extent there about 1750, when general
melting began. The advance or retreat of glacier snout
reflects many factors: snowfall rate, topography and climate
trends. Most glacier in every mountain range in Alaska are
experiencing significant retreat, thinning or stagnation.
Today, glacial retreat continues on the bays east and
southwest sides, on the west side several glaciers are
actually stable or advancing fed by copious snowfall high in
