Glacial hazards in Glacier National Park, Montana

Auteur :
BUTLER, D. R.

Description :
Ice avalanches were more common and more widely distributed during and immediately after the Little Ice Age. As glaciers and the threat of ice avalanching have receded in the twentieth century, the potential for debris flows from moraine-dammed lakes has risen. Glacial calving, slope instability, rapid snowmelt, and intense thunderstorms provide potential triggers for debris flows in the Park, some of which could produce catastrophic maximum discharges.
