a Nevada, California, using an airborne imaging spectrometer, to determine if these materials could be uniquely identified with reflectance spectroscopy. Such information can be used to prepare or refine maps of areas that may contain minerals that can be asbestiform, such as serpentine and amphiboles, which were the focus of the study by Swayze et al. Although thick vegetation can conceal underlying rock and soil, use of modeled spectra of dry grass and serpentine allowed detection of serpentine in some parts of the study area with up to about 80% dry-grass cover. Chaparral vegetation, which was dominantly, but not exclusively, found in areas underlain by serpentinized ultramafic rocks, was also mapped. Practical applications of this technology for mapping areas that may contain NOA include locating roads that are surfaced with serpentine aggregate, identifying sites that may require enhanced dust control or other safety measures, and filling gaps in geologic mapping where field access is limited.

GSA Today Science Article The Klondike goldfields and Pleistocene environments of Beringia
Duane Froese et al., Dept. of Earth and Atmospheric Sciences, Univ. of Alberta, Edmonton, Alberta, T6G 2E3, Canada

Declining sea level during the last great glacial event resulted in the exposure of a continuous land bridge extending from Siberia in the west to Yukon in the east. Lying in the rain shadow of the St. Elias Mountains, this great region, now known as Beringia, was cold but too dry for the development of glaciers. Instead, the region consisted of a great Arctic steppe, bound by mountains to the south and continental glaciers to the north, west, and east. This vast plain was a veritable Serengeti, host to megafauna like the steppe bison, woolly mammoth, Yukon horse, western c
