From left, the glacier is seen in June 5, 1980, May 16, 1989, and May 13, 2011. The thick covering of sediment on the stagnant glacier helped to insulate the underlying ice, helping to preserve it and prolonging the time it took to melt. It originates on land from the accumula-tion, compaction, and recrystallization of snow. If you dug down into the accumulation zone of a glacier, you would find three main layers. smallest type of glacier; forms in small bowl-like depressions in the mountains; also called alpine glaciers.
