“…The early work of Mercer and Palacios (1977) provides evidence that ice advanced near Quelccaya near the start and end of the YD. Similarly, Kelly et al (2015) provide additional radiocarbon-based evidence that the Quelccaya Ice Cap advanced at the start of the YD, followed by retreat.…”

“…Field mapping combined with TCN sampling yielded 10Be dates (n=12) from two field sites, Laguna Acrimona and Minas Tira, that range from 26 ka to 15 ka (Bromley et al, 2016). These ages were derived by applying the new high elevation tropical production rate calibrated at nearby Quelccaya (Kelly et al, 2015) and significantly affirm that the most extensive advance of the last glacial cycle pre-dates the LGM.…”

“…In the case of Illimani (Smith et al, 2011), ages were not available in the Shakun et al (2015a) composite, and we recalculated with the Quelccaya 10 Be production rate calibration (Kelly et al, 2015), and the CRONUS-Earth calculator version 2.3 with the time-invariant 'St' scaling method of Stone (2000) following Lal (1991). Newly published data from the Cordillera Carabaya (Bromley et al, 2016) and Nevado Huaguruncho (Stansell et al, 2015) were calculated by the authors using the Quelccaya production rates.…”

“…Late Holocene moraines were also dated in high detail (Stroup et al, 2014). Ample material for maximum and minimum dates constrain a date of 12.35 ka for H2a moraine, allowing for 10 Be production rates to be calculated (Kelly et al, 2015). Bromley et al (2009) conducted thorough geomorphological field mapping on Coropuna, and published a map of glacial deposits, along with 3 H ages for LGM and Late Glacial ages.…”

ABSTRACT. The tropical Andes of Peru and Bolivia are important for preserving geomorphic evidence of multiple glaciations, allowing for refinements of chronology to aid in understanding climate dynamics at a key location between hemispheres. This review focuses on the deglaciation from Late-Pleistocene maximum positions near the global Last Glacial Maximum (LGM). We synthesize the results of the most recent published glacial geologic studies from 12 mountain ranges or regions within

Despite a large number of dated glacial landforms in the Himalaya, the ice extent during the global Last Glacial Maximum (LGM) from 19 to 23 ka is only known to first order. New cosmogenic 10Be exposure ages from well‐preserved glacially polished surfaces, combined with published data, and an improved production rate scaling model allow reconstruction of the LGM ice extent and subsequent deglaciation in the Chandra Valley of NW India. We show that a >1000 m thick valley glacier retreated >150 km within a few thousand years after the onset of LGM deglaciation. By comparing the recession of the Chandra Valley Glacier and other Himalayan glaciers with those of Northern and Southern Hemisphere glaciers, we demonstrate that post‐LGM deglaciation was similar and nearly finished prior to the Bølling/Allerød interstadial. Our study supports the view that many Himalayan glaciers advanced during the LGM, likely in response to global variations in temperature.
