Craig Lee holds the ice drill with the end of the first ice core segment exposed.  The sample will next be measured, logged, and processed in the field.

Spring sampling location along Little Sandy River in southern Wyoming. Groundwater discharge that flows into the Upper Colorado River Basin varies in response to drought, which is likely due to aquifer systems that contain relatively young groundwater, according to a new U.S.
