Highlights
- A suite of metals was measured in snowpacks from the Rocky Mountain region.
- Lanthanum and cerium concentrations support mineral dust to southern sites.
- Antimony, cadmium, mercury, and zinc support anthropogenic sources to northern sites.
- Temporally consistent contaminant sources and/or transport processes were observed.
- Contaminant sources potentially include current and historical mining, and smelting.
