Piedmont glaciers can exhibit distinct features such as crevasses and seracs, which are formed due to differential movement within the glacier. Due to climate change and rising temperatures, many piedmont glaciers are retreating at accelerated rates, impacting local ecosystems and water supply.
5 sty 2022 · Understanding the surges and retreats of Alaska's Malaspina Glacier is key if climate change models are to be applied to the glacier with confidence.
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.
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.
4 kwi 2017 · Piedmont glaciers form when steep valley glaciers spill out into relatively flat plains. Unchained from the constraints of the terrain, the ice flows freely in all directions. Image Credit: NASA Earth Observatory/ASTER/Jesse Allen

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.
