An isotopic paleotemperature record for late Wisconsinan time in northeast Iowa
Abstract
Isotopic temperatures and 230Th/234U ages have been determined for a stalagmite from Cold Water Cave, Iowa, some 50 km west of the Driftless Area. Calcite is now being deposited in this cave under conditions of isotopic equilibrium. The stalagmite, which was continuously deposited during the interval 25,000 to 6000 B.P., shows a pronounced temperature minimum at about 17,000 ± 2000 B.P. This is synchronous with the maximum Woodfordian advance …
