Glacier Bay National Park By: Fatimah
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 Fair-weather Mountains
