National Park Glaciers

Ample shade, blowing snow, and steady cold temperatures are creating a "perfect situation" for four small park glaciers in Rocky Mountain National Park.

Independent researcher and geologist Jon Achuff says the glaciers haven't dramatically changed since the 1930s based on photo comparisons.

The glaciers provide late-season runoff to park streams after snow has melted.

Even while the climate gets warmer, the glaciers aren't being affected by it because they get little direct sunlight.

Nel Caine, a geography professor at the University of Colorado, says the glaciers are so small that they respond more to extremely localized climate patterns than they will to global trends.

Achuff estimates the glaciers at about 20 acres each.
