Caption

New University of Utah research found that dust deposition speeds up snowmelt in Utah's Wasatch Mountains. A single dust storm on April 13-14, 2017, deposited half of all dust for the season. The additional sunlight absorbed by the dust-darkened snow surface led to snow melting a week earlier.
