* The JEOL superprobe was operated at 15 keV accelerating voltage, 10 micron beam diameter, and 6 nA beam current. Standardized to obsidian standard UA5831 and recast to 100% on a water-free basis; (#) = standard deviation; FeOt = total iron oxide as FeO; H2Od = water by difference. Uaxxxx = University of Alberta Tephrochronology Lab accession number; n = shards analyzed. SC-F, Sheep Creek-F; OC, Old Crow tephra. UA1471 experienced Na loss during analyses. Identification as Old Crow tephra was confirmed by comparison to a reference sample that was analyzed during the same instrumental run. *
