Fewer frozen-over days expected to future for rivers in NPs, other PAs in Rocky Mountains

Rivers in the Rocky Mountains that typically freeze over during winter are expected to see fewer days of being frozen as the climate continues to warm, according to researchers at the University of North Carolina-Chapel Hill. Many streams in Rocky Mountain, Grand Teton, Yellowstone, and Glacier national parks likely will be affected.

If you've ever made it out to Avalanche Lake in Glacier during the winter, you've no doubt admired the long, icy tendrils of vertical rivers that stream down the rimming mountains.
