Description :
The AA. present radiocarbon ages of sediments underlying and within the Guadalupe dune sheet, where uplift rates are zero or less, indicate that estuarine deposition began locally around 9-11 ka in response to rising sea level. The estuarine deposits where then buried by dune sands around 3.5-4.3 ka, perhaps in response to sea-level regression during mid-Holocene (-4.5 ka) glaciation and not the earlier glacial periods, as previously inferred by others.
