Strahler, Glacial Deposits, formed a Work Group on Glacial Tectonics(WGGT) in 1987. Dr. J. Aber served as the overall coordinatorfor North America. By 1993 Aber had compiled an extensivebibliography consisti Glacial Ice. . Once . glacial ice exceeds a thickness of about 150 feet, the weight of the overlying ice causes . the . base of . the glacier . to become plastic and flow like a very viscous liquid. While the bottom ice responds as a plastic solid, the surface ice is very brittle. However, from the surface down to the top of the plastic portion of the glacier, the ice experiences a decrease in . Glacial Erosion. As glaciers travel over land, glacial ice can erode the underlying bedrock.. This erosion can happen by:. Plucking. A. brasion. Plucking. This occurs when melt water at the base of the glacier freezes in cracks and fractures the underlying bedrock.. Lateral moraine. Braided streams. Medial moraine.

Study context. The . Drac. valley is located in the Western French Alps. The valley is located at the border of the Alpine glaciated area and was influenced by repeated base-level fluctuations due to glacial damming. This had led to repeated cycles of valley filling and re-incision, which potentially hold important information on the climatic control on fluvial and glacial dynamics in the region.
