Snow in the Upper Colorado River Basin provides water for seven states.  Farmers, factories, and families alike depend on this water, and a considerable amount of effort goes into understanding and forecasting how much melt is going to come from the snowpack, and when.

If you’ve ventured out on a hot day wearing dark clothing you know that within a short time you're soaked with sweat. Similarly, when a blanket of dust settles on snow, it acts the same way - the snow sweats or melts. The result is a rapid melting of snow.  Aspen Public Radio’s Science Reporter Ellis Robinson has more.

Living in the mountains, it’s easy to see changes in nature, especially in the snow. In recent years, dust from desert areas like Utah, has coated some of the area’s snowpack. Scientists in Boulder say the amount of dust being blown into Colorado and throughout the West, has increased over the last two decades. They measured calcium in rainfall to come up with their findings. Jason Neff is associate professor of geology at CU-Boulder and coauthor of the dust study. He told Aspen Public Radio's Marci Krivonen the escalation of dust emissions is due to several factors.
