Glaciologists measure, model hard glacier beds, write slip law to estimate glacier speeds

The field photos show the hard, rough country that some glaciers slide over: rocky domes and bumps in granite, rocky steps and depressions in limestone. The glacier beds dwarf the researchers and their instruments. (As do ...
