Scientists, tribe study shrinking Washington state glacier

Mauri Pelto digs his crampons into the steep icy slope on Mount Baker in Washington state and watches as streams of water cascade off the thick mass of bare, bluish ice. Every 20 yards, the water carves vertical channels in the face of the glacier as it rushes downstream.

What little snow from last winter is already gone, so ice is melting off the glacier at a rate of nearly three inches a day this summer, he said.
