University of Idaho geologist Erika Rader uses a portable visible near-infrared spectrometer at the Lost Jim lava flow to measure the amount of light reflected by the lava flow surface. The amount of light tells us how crystalline or glassy the lava flow is, which is useful for understanding the cooling history of lava erupted into the unique arctic environment.
