Preliminary Results of Growth Rate and Paleoclimate Studies of a Stalagmite from Ogle Cave, New Mexico
Russell S. Harmon and Rane L. Curl

Abstract

230Th/234U dating and morphologic study of a portion of a stalagmite from Ogle Cave, New Mexico indicates continuous depositon from about 205,000 to 125,000 years BP. This is the period to which is commonly assigned the penultimate glaciation in North America, suggesting that deposition of speleothems in arid areas of the western United States was more intense during the pluvial periods accompanying glaciation than at present.
