Glacial buzzsaw
The glacial buzzsaw is a
valley glaciers may easily surpass the equilibrium line altitude and do therefore not contribute to a glacial buzzsaw effect.[2][3] This is said to be the case of the Patagonian ice fields where lack of buzzsaw effect results in rapid tectonic uplift rates.[1]
Mountains massifs proposed to be subject to a glacial buzzsaw effect include the mountains of southeast Alaska, the Teton Range of Wyoming and the Dauphiné Alps of France.[1] Authors such as Egholm and co-workers have claimed that the glacial buzzsaw effect can explain mountain altitudes across the globe.[1] Some of the mountain massifs experiencing the highest uplift rates are those for which glacial buzzsaw effects are discarded.
The concept has been criticized, as measured erosion ratesWest Greenland are also unrelated to any glacial buzzsaw effect.[5]
