Late Pleistocene glacial deposits, non-glacial deposits emplaced in the mid-Holocene, and late-Holocene glacial deposits are described and discussed in relation to absolute and relative dating methods employed to place them in the geologic column. Younger deposits of Neoglacial age cannot be dated by radiocarbon owing to the scarcity of organic materials. The degree of soil development in older radiometrically dated deposits, compared with the younger Neoglacial deposits, suggests that the latter group has an age of <1000 years BP. Mid-Holocene deposits comprising the Darwin Formation have been dated by 14 C; variable soil morphologies in these materials give an indication of the dual roles of climate and time insofar as they affect soil genesis in the Afroalpine area. Older late glacial deposits appear to have been free of ice at least 12 500 yrs BP. Soils formed in these late glacial deposits make up the post-Liki III soil stratigraphic unit, which comprises an important time marker in the late glacial/postglacial chronology of the Mount Kenya Afroalpine area. The landform-soil chronology correlates broadly with the pollen chronology previously determined for the Sacred Lake area. Minor differences in climate inferred from the two lines of evidence are thought to result either from variations in the magnitude of climate change between 2440 and ~4000 m, or from different timing for events of similar magnitude.
