Abstract This work presents the first reconstruction of late Pleistocene glacier fluctuations on Uturuncu volcano, in the Southern Tropical Andes. Cosmogenic 3He dating of glacial landforms provides constraints on ancient glacier position between 65 and 14 ka. Despite important scatter in the exposure ages on the oldest moraines, probably resulting from pre-exposure, these 3He data constrain the timing of the moraine deposits and subsequent glacier recessions: the Uturuncu glacier may have… 
Late Pleistocene glaciations of the arid subtropical Andes and new results from the Chajnantor Plateau, northern Chile
Abstract The spatiotemporal pattern of glaciation along the Andes Mountains is an important proxy record reflecting the varying influence of global and regional circulation features on South American
Prospecting Glacial Ages and Paleoclimatic Reconstructions Northeastward of Nevado Coropuna (16° S, 73° W, 6377 m), Arid Tropical Andes
This work investigates the timing, paleoclimatic framework and inter-hemispheric teleconnections inferred from the glaciers last maximum extension and the deglaciation onset in the Arid Tropical
Late Pleistocene glacial fluctuations in Cordillera Oriental, subtropical Andes
Abstract The behavior of subtropical glaciers during Middle to Late Pleistocene global glacial maxima and abrupt climate change events, specifically in Earth's most arid low-latitude regions, remains
A preliminary investigation of the timing of the local last glacial maximum and deglaciation on HualcaHualca volcano - Patapampa Altiplano (arid Central Andes, Peru)
Abstract We studied the timing and area of the late Pleistocene maximum glacier extent, the readvance or stillstand phases and the deglaciation processes in the HualcaHualca volcano and Patapampa
Glacial chronology and production rate cross-calibration of five cosmogenic nuclide and mineral systems from the southern Central Andean Plateau
Abstract Glacial deposits on the high-altitude, arid southern Central Andean Plateau (CAP), the Puna in northwestern Argentina, document past changes in climate, but the associated geomorphic
The deglaciation of the Americas during the Last Glacial Termination
Abstract This paper reviews current understanding of deglaciation in North, Central and South America from the Last Glacial Maximum to the beginning of the Holocene. Together with paleoclimatic and
Timing of past glaciation at the Sierra de Aconquija, northwestern Argentina, and throughout the Central Andes
Abstract Advances in cosmogenic nuclide exposure dating have made moraines valuable terrestrial recorders of palaeoclimate. A growing number of moraine chronologies reported from the Central Andes
A major advance of tropical Andean glaciers during the Antarctic cold reversal
A new 10Be moraine chronology in Colombia is presented showing that glaciers in the northern tropical Andes expanded to a larger extent during the Antarcticcold reversal than during the Younger Dryas, and argues for a common glacier response to cold conditions in the Antarctic cold reversal exceeding that of the Younger dryas.
Across the Arid Diagonal: deglaciation of the western Andean Cordillera in southwest Bolivia and northern Chile
Here we review published cosmogenic records of glaciation and deglaciation from the western cordillera of the arid subtropical Andes of northern Chile and southwest Bolivia. Specifically, we examine
Antarctic-like temperature variations in the Tropical Andes recorded by glaciers and lakes during the last deglaciation
Abstract The respective impacts of Northern and Southern Hemispheric climatic changes on the Tropics during the last deglaciation remain poorly understood. In the High Tropical Andes, the Antarctic


Late local glacial maximum in the Central Altiplano triggered by cold and locally-wet conditions during the paleolake Tauca episode (17–15 ka, Heinrich 1)
The timing and causes of the last deglaciation in the southern tropical Andes is poorly known. In the Central Altiplano, recent studies have focused on whether this tropical highland was deglaciated
Cosmogenic 10Be and 26Al exposure ages of moraines in the Rakaia Valley, New Zealand and the nature of the last termination in New Zealand glacial systems
New Zealand glaciers reached their last glacial maximum position at or before ~ 25 ka, and, as early as 23 ka, commenced a slow and continual retreat. New cosmogenic exposure ages and field mapping
Late Quaternary glacial history in the Encierro Valley, northern Chile (29°S), deduced from 10Be surface exposure dating
Abstract The Late Pleistocene glacial and climate history in the dry Central Andes is not well known so far, mainly because of the lack of suitable material for radiocarbon dating. In order to
Late Quaternary glacier advances and palaeolake highstands in the Bolivian Altiplano
Abstract Recent study of late Quaternary moraines and ‘pluvio’-lacustrine features around the southern Altiplano of Bolivia suggests they developed more or less synchronously during the last glacial
LGM and Late Glacial glacier advances in the Cordillera Real and Cochabamba (Bolivia) deduced from 10 Be surface exposure dating
Abstract. Surface exposure dating (SED) is an innovative tool already being widely applied for moraine dating and for Late Quaternary glacier and climate reconstruction. Here we present exposure ages

Geochronology and stratigraphy of late Pleistocene lake cycles on the southern Bolivian Altiplano: Implications for causes of tropical climate change
Large paleolakes (∼33,000–60,000 km2) that once occupied the high-altitude Poopo, Coipasa, and Uyuni Basins in southern Bolivia (18–22°S) provide evidence of major changes in low-latitude moisture.
