Timing of late Quaternary glaciations south of Mount Everest in the KhumbuHimal, Nepal

Moraines south of Mount Everest in the Khumbu Himal were dated using optica lly stimulated luminescence. Clustering of ages and morphostratigraphy allo wed three advances to be dated: (1) the Periche Glacial Stage (ca. 18-25 ka ), (2) the Chhukung Glacial Stage (ca. 10 ha), and (3) the Lohuche Stage (c a. 1-2 ha). The Periche Stage is coincident with Oxygen Isotope Stage 2; th e Chhukung Stage represents a late glacial or early Holocene glacial advanc e; and the Lohuche Stage is a late Holocene glacial advance that predates t he Little Ice Age.
