Uturuncu currently features no glaciers; however, perennial ice was reported in 1956, the existence of sporadic snow fields in 1994, and the summit area is occasionally ice-covered. Conversely, evidence of past glaciation such as glacial striations, glacially eroded valleys, both recessional and terminal moraines and roches moutonnées can be found on the northern, eastern and southern flanks of Uturuncu. The past glaciation of Uturuncu was not very extensive, owing to its steep flanks. One of these valleys on Uturuncu's southwestern flank has been subject to glaciology studies, which identified a former glacier originating both from the summit and from an area about south of the summit.
