No connection with mountain foot; up to 60 deg slope; Perched on a steep mountain-side or issuing from a hanging valley (WGMS, 1970); Perched on a steep mountain-side or issuing from a steep hanging v
alley (WGMS, 1977)
A glacier that originates high on the wall of a glacier valley and descends only part of the way to the surface of the main glacier. Avalanching and icefalls are the mechanisms for ice and snow transf
er to the valley floor below.
A secondary valley that enters a main valley at an elevation well above the main valley's floor. These features are result of past erosion caused by alpine glaciers. Hanging valleys are often the site
of spectacular waterfalls.
A former tributary glacier valley that is incised into the upper part of a U-shaped glacier valley, higher than the floor of the main valley. Hanging valley streams often enter the main valley as wate
rfalls.
A tributary valley whose mouth ends abruptly part way up the side of a trunk valley, as a result of the greater amount of glacial down-cutting of the latter.
