Ladywriter 7,783 Report post Posted April 12, 2010 Expert: Many of the last 25 icefields could be gone by 2020 BILLINGS, Mont. - Glacier National Park has lost two more of its namesake moving icefields to climate change, which is shrinking the rivers of ice until they grind to a halt, a government researcher said Wednesday.Warmer temperatures have reduced the number of named glaciers in the northwestern Montana park to 25, said Dan Fagre said, an ecologist with the U.S. Geological Survey. He warned many of the rest of the glaciers may be gone by the end of the decade. "It's continual," Fagre said. "When we're measuring glacier margins, by the time we go home the glacier is already smaller than what we've measured."

The park's glaciers have been slowly melting away since about 1850, when the centuries-long Little Ice Age ended. They once numbered as many as 150, and 37 of those glaciers eventually were named. A glacier needs to be 25 acres to qualify for the title. The two that no longer classify were named the Shepard Glacier and the Miche Wabun Glacier.
