Piedmont glaciers occur when valley glaciers spill into relatively flat plains, where they spread out into bulb-like lobes. Malaspina Glacier in Alaska is one of the most famous examples of this type of glacier, and is the largest piedmont glacier in the world.
ice sheet. ice shelf, thick mass of floating ice that is attached to land, formed from and fed by tongues of glaciers extending outward from the land into sheltered waters. Where there are no strong currents, the ice becomes partly grounded on the sea bottom and attaches itself to rocks and islands.
6 lut 2021 · North of the Gallegos River valley, glacigenic deposits outcrop in two altimetric levels. The Meseta Latorre is the highest level (1,064 m a.s.l.), a relic of the ancient Andean piedmont.
piedmont glacier. large ice lobe spread out over surrounding terrain, associated with the terminus of a large mountain valley glacier. The massive lobe of Malaspina Glacier in Alaska is clearly visible in this photograph taken from a Space Shuttle flight in 1989.
1 sty 2014 · Definition. A valley or outlet glacier exhibiting a lobe- or fan-shaped section (“piedmont lobe”) immediately beyond the confining valley mouth, where the ice tongue emanates onto an unconstrained, lower slope angle terrain (Stroeven 2013). Valley glaciers may coalesce to form large, multilobate piedmont glaciers.
30 paź 2022 · Piedmont glaciers are formed when a glacier leaves the laterally constricting relief of a mountain range in order to then flow out in all directions in the foreland with little relief. Piedmont glaciers are not independent glaciers, but only parts of a larger glacier or glacier system.
