    • J. Hellstrom, M. McCulloch, and J. Stone (Quat. Res., in press) recognize an oxygen isotope excursion that initiated 700 years before the YD, which they interpret as a glacial advance and then correlate it to the Waiho Loop sequence. Carbon isotope data show strong revegetation at about 13,000 radiocarbon years ago with no signal of a YD change in vegetation.

This circulation ceased about 14,000 years ago according to Blanchon and Shaw (15), who suggest that a rapid lowering of the Laurentide Ice Sheet allowed the Northern Hemisphere polar jet to readopt a northerly track. Reexpansion of the Laurentide Ice Sheet due to glacio-isostatic rebound and enhanced accumulation caused the LGM pattern to reestablish at 11,000 years B.P., triggering the YD in their model.
