Problem: There are at least 35 named glaciers in Glacier National Park (U.S.). In 1850, the area now comprising the national park had 150 glaciers. There are 25 active glaciers remaining in the park today. Since the ice ages stopped 10,000 years ago, there have been many slight climate shifts causing periods of glacier growth or melt-back. The glaciers are currently being studied to see the effect of global warming It is estimated that if current warming trends continue, there will be no glaciers left in the park by 2030.

Solution: is there a glacier in glacier national park?
