aldalöngu

aldalöngu is an Icelandic term that translates literally to "long valley." It is primarily used in geography to describe a specific type of glacial valley found in Iceland. These valleys are characterized by their elongated and relatively narrow shape, often with steep sides and a U-shaped cross-section, a typical feature carved by glacial erosion. aldalöngu are a common landscape element in many of Iceland's highland regions and along its coasts, where glaciers have historically been or continue to be present. The formation process involves the slow, persistent movement of ice over long periods, grinding away at the bedrock and widening and deepening existing river valleys. These valleys can be quite extensive, stretching for many kilometers. The term is not exclusive to Iceland but is specifically applied to these formations within the Icelandic context. The geological processes that create and shape aldalöngu are fundamental to understanding Iceland's dramatic and dynamic landscape.
