Can use landform evidence to find glacier erosion rates - reconstruct preglacial landscape and compare to adjacent eroded landscape
Nesje et al 1992
Results of glacier erosion rates:
Iceland/France = 0.9 mm/a basalt, 36 mm/a marble
Boulton 1974
Results of glacier erosion rates:
Sognefjord W Norway = 1 mm/a over 600,000 years (FAST)
Nesje et al 1992
Results of glacier erosion rates:
Polar glaciers 0.01mm/a
Small temperate glaciers (Alps) 1 mm/a
Large flowing glaciers (Alaska) 10-100 mm/a
