Tracing Dust Deposition Along the Wasatch Front
The Great Salt lake (GSL) and other playas in Northern Utah contribute dust to the Wasatch Front. The goal of this project is to quantify the amount of dust that comes from the GSL lakebed and other dust sources. 40 samples were taken over the course one year at potential source and deposition sites. Sample source sites include various playas extending from Sevier Dry Lake to Antelope Island. Sample deposition sites include snow sites in Little Cottonwood Canyon and the Uinta Mountains, and college campus sites of Provo, Salt Lake City, Ogden, and Logan. Results show increased amounts of the following elements at both source and deposition site: Li, Na, U, Sr, Mo, Ca and Ti, which means that these elements could help determine specific playas contributing to the Wasatch Front. Higher quantities of elements at sample dust collection source is seen with all other elements, which means that the remaining elements likely come from local and anthropogenic sources.
