...) ages from 14,200–12,600 yr cal. Lower strandlines are younger, but the similarity of ages suggests that initial lake lowering was faster than OSL ages can currently resolve. Nevertheless, the OSL ages represent the first numerical age assignments for the Herman, Norcross, and Upham beach ridges...

(A) Simplified geologic cross section extending from the southern boundary of the Valley and Ridge physiographic province to the pin line on the Appalachian Plateau. (B) Restored cross section from X–X′ highlighting the 28% discrepancy in the restored line lengths between imbricated carbonate sequence and overlying mainly folded strata. Cross section is simplified from Herman (1984). LPS—layer-parallel shortening.

Simplified geological setting (a) and geological map of Gibbs Island (b). (a) is after Maldonado et al. (2006), and (b) is after de Wit et al. (1977) and Grunow et al. (1992).

... history. Using geomorphic relationships and OSL age control, it is proposed that the Herman through Tintah strandlines developed over a period of <1000 years followed by a hiatus of strandline development until the Campbell strandline developed at 10.3 ± 0.2 ka cal. There is agreement between our new...
