We measured Sr-Nd-Pb isotope ratios of impurities filtered from an elevational transect of surface snow pits (2180–5240 m a.s.l) sampled in June 2016 in the Alaska Range of Denali National Park, Alaska to investigate the sources of dust and pollution aerosols. Comparable measurements on 20 fine-grained glaciofluvial silt and loess samples from southcentral Alaska and the Kluane Lake region of Yukon, Canada, were developed to characterize the local glaciogenic dust source composition. The dataset includes 87Sr/86Sr, 143Nd/144Nd, epsilon Nd, 206Pb/204Pb, 207Pb/204Pb, 208Pb/204Pb, 206Pb/207Pb, and 208Pb/207Pb ratios.
