Proglacial valleys of the St. Elias Mountains in western Canada are major sources of historical mineral dust emissions, as evidenced through loess records, yet no estimates of contemporary emissions exist for this region. In these landscapes, dust emissions occur at the interface of glaciofluvial an...
