Part 2: NPR on dusting the Rockies from Utah

Good interview with Joyce Belnap, leading specialist in desert soil microbes that hold the soil together. When these microbes or crytopograms are run over by Jeeps, ATV's, bikes, or smashed by hooves of cows, the soil breaks loose and blows away. The dust settles on snow pack in the Rockies and makes the snow melt faster, creating havoc with managing reservoirs and thus the water supply for the Front Range.
