Abstract
Moraines at ~ 4000 m on Mount Kenya have been assigned a mid-Holocene age by Johansson and Holmgren (1985) who consider that these moraines result from advances of Holocene ice out of local cirques. New evidence presented here shows that moraines at ~ 4200 m a.s.l. are the result of stillstand following recession of Liki (Würm Wisconsin) ice on Mount Kenya. The minimum radiocarbon ages from part of a suite of bog sediments, associated with Liki moraines in Teleki Valley, are approximately ~ 12,000 yr BP, placing them at least within the late glacial. The implications, for reconstruction of late Pleistocene and Holocene paleoclimate, are that no early or mid-Holocene glacial advances occurred, and equilibrium line altitudes (ELA's) of most cirque glaciers fluctuated by no more than 100 m during the Neoglacial, which began at ~ 1000 yr BP.Keywords
