Workshop on Glacial Overdeepening; Zurich, Switzerland, 20–21 April 2012 Glacially overdeepened valleys and basins are common features in high mountain belts and their forelands. These overdeepenings are of practical and scientific interest, representing sites of potential lake formation; influencing the dynamics and hydrology of ice masses; presenting opportunities for glacial and climate reconstruction; and raising management issues related to aggregate, groundwater, and hydrocarbon resources and radioactive waste disposal in deep geological repositories. Although the basic principles of glacial erosion are generally known, the formation of overdeepened valleys beneath glaciers and ice sheets remains incompletely understood.
