With the purpose of establishing the recent glacial chronology of the HPN, moraines at Glaciar Exploradores were identified and investigated, thereby collecting samples for +.C dating. In total, three moraine systems were recognized, the Invernada moraine (TM+), main moraine (TM,) and the modern (secondary) moraines (TM-). TM- was further subdivided into TM-+ and TM-, based on vegetation cover, size, morphology, degree of rock weathering, and development of mosses on rocks. Two samples from TM+, six samples from TM, and seven samples from TM- were dated. Also the number of tree rings was counted at TM, and TM-. Based on these data, four possible scenarios were postulated and examined. The tentative conclusion is that there were two recent glacial advances at Glaciar Exploradores, one sometime between the +,th and +1th century (forming main moraine, TM,) and the other around the early to mid-+3th century (TM-+) and after ca. +3.. (TM-,). We could not obtain a date that would indicate the age of the Invernada moraine (TM+): however, from the age of TM,, it was speculated that it could be of the Neoglaciation III (+0**+-** BP).
