A new glacial chronology for equatorial East Africa is developed using in situ cosmogenic 36Cl measured in 122 boulders from moraines on Mount Kenya and Kilimanjaro. The oldest deposits sampled on Kilimanjaro yield a limiting 36Cl age of s 360 calendar kyr (all 36Cl ages are in calendar years, cal. kyr or cal. yr). On Mount Kenya, the oldest moraines give ages of 355^420 kyr (Liki I) and 255^28...

Topography exerts a strong control on how glaciers respond to changes in climate. Increased understanding of this role is important for both refining model predictions future rates glacier recession and reconstructing climatic change from the glacial geological record. In paper, we examine geomorphological sedimentological evidence foreland Fingerbreen, temperate outlet plateau icefield Østre S...
