Description


I took this photo from the SE side of the Taku Inlet, July 1986. We are looking at the Brassiere Hills and the Taku Glacier ran, right to left, behind these hills since the beginning of time. This glacier is so thick, that it overflowed between the two Brassiere Hills. This glacial tributary was nicknamed the Hole in the Wall Glacier. Zoom to see that this new glacier moved up and over the land bridge between the two hills and down into the inlet. The Taku Glacier, still moves SW, entering the inlet, near where the inlet meets the ocean. The peak in the background is Amherst Peak, if my memory is any good. This photo was scanned. HISTORY: Taku Glacier, just SE of the city of Juneau, is a tidewater glacier located in Taku Inlet, in the US state of Alaska,. Recognized as the deepest and thickest glacier known in the world, the Taku Glacier is measured at 4,845 feet (1,477 meters) thick. The glacier was originally named Schultze Glacier in 1883 and the Foster Glacier in 1890, but Taku, the name the local Tlingit natives had for the glacier, eventually stuck. It is nestled in the Coast Mountains and originates in the Juneau Icefield. It is the largest glacier in the Juneau Icefield and one of the southernmost tidewater glaciers of the northern hemisphere. The glacier, which converges with the Taku River at Taku Inlet, has a history of advancing until it blocks the river, creating Taku Lake, followed by a dramatic break of the ice dam. The most recent of these advances occurred in 1750. The glacier has advanced 4.66 miles (7.5 km) since 1890. It is the only advancing glacier of the 20 major glaciers of the Juneau Icefield. If the advance continues it will again block the river. Since 1946, the glacier has been advancingand since 1988, at 56 feet (17 meters) a year. The advance is due to a positive mass balance; that is, more snow accumulates than snow and ice melt. The peak in the background is Amherst Peak, if my memory is any good.

Great vivid example of glaciation! I live in one of the world oldest glaciated landscapes just up the road is a lake with these rounded rock edges!
