The longest ice river in North America, this 76-mile stretch of glacier water begins at Mount Logan in Canada’s Yukon and meanders its way through Alaska to the Russell Fjord Wilderness. In 2002 the advancing terminus of Hubbard Glacier created a glacier lake dam which turned Russell Fiord in to a lake for about two and a half months. Their movement, though much slower, is comparable to the flow of a river. Twice in the past hundred years—in 1986 and again in 2002—the moraine has made contact with Gilbert Point and blocked the entrance to Russell Fjord. A cirque glacier is formed in a cirque, which is a bowl-shaped depression on the side or top of mountains. - Definition, Types & Examples, ICSE Environmental Science: Study Guide & Syllabus, UExcel Microbiology: Study Guide & Test Prep, High School Chemistry: Homework Help Resource, AP Environmental Science: Help and Review, College Chemistry: Homework Help Resource, Prentice Hall Biology: Online Textbook Help, AP Environmental Science: Tutoring Solution, AP Environmental Science: Homeschool Curriculum, Biological and Biomedical According to the National Park Service, the advance is due to global warming which causes more precipitation to fall in the St. Elias Mountains.

In geology, a proglacial lake is a lake formed either by the damming action of a moraine during the retreat of a melting glacier, a glacial ice dam, or by meltwater trapped against an ice sheet due to isostatic depression of the crust around the ice.
