• In this study the age of the onset of passage development and the timing of sedimentation in the cave passages at the Cave of the Winds, Manitou Springs, Colorado are determined. The amino acid rations of land snails located in nearby radiometrically dated alluvial terraces and an alluvial terrace geomorphically associated with Cave of the Winds were used to construct an aminostratigraphic record. This indicated that the terrace was ~ 2 Ma. The age of the terrace and its geomorphic relation to the Cave of the Winds was use to calibrate the magnetostratigraphy of a 10 meter thick cave sediment sequence. The results indicated that cave dissolution started ~4.5 Ma and cave clastic sedimentation stopped ~1.5 Ma.
