BYU geologists investigating increase in dust

Geologists at Brigham Young University are putting the blame for increased dust in northern Utah on a drier, drought-ridden climate.

In a new study, researchers concluded that 90-percent of the dust blown in the region comes off land that came from shrinking bodies of water such as the Great Salt Lake and Sevier Lake.

The higher dust levels are leading to higher air pollution levels.

Scientists says the increased dust also reduces snow's ability to reflect heat.
