Summary:: Loess and dune sands on the northwest flank of Mauna Kea volcano are studied. Radiocarbon ages of charcoal fragments within the loess, U-series ages of rhizoliths in the dune sand, and K/Ar ages and relative stratigraphic positions of lava flows provide a stratigraphic and temporal framework. The research suggests that vents upslope from the sand dunes were the primary source of the eolian sediments. Average paleowind directions during the eruptive interval (ca. 50,000-15,000 yr B.P.)suggest that Mauna Kea has remained within the tradewind belt since before the last glaciation.
