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.
6 lut 2021 · Abstract. 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. A degraded basal moraine and a frontal/lateral ridge occupy the summit of the tableland.

9 lut 2018 · Valley and piedmont glaciers originate in the high alpine and terminate on land. They often flow through deep bedrock valleys that confine the ice on either side. Over time, they carve and shape these valleys (see U-Shaped Glacial Valleys).
18 paź 2024 · Figure 3.30.1 3.30. 1: Cross-section of a valley glacier showing stress (red numbers) increases with depth under the ice. The ice will deform and flow where the stress is greater than 100 kilopascals, and the relative extent of that deformation is depicted by the red arrows. Downslope movement is shown with blue arrows.
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.
