There is evidence that the McGinnis Glacier, a little-known tongue of ice in the central Alaska Range, has surged. Assistant Professor of Physics Martin Truffer noticed the lower portion of the glacier was covered in cracks, crevasses, and pinnacles of ice—all telltale signs that the glacier has recently slid forward at higher than normal rates. It has not been determined whether the glacier continues to surge.

Fairbanks, Alaska— University of Alaska Fairbanks scientists will travel to Greenland in April 2010 to better understand how warming ocean temperatures impact ocean-outlet glaciers on the massive arctic island. Such studies will shed light on the future of the ice-laden country, and may provide analogs on how warmer temperatures could impact Alaska’s landscape.
