Abstract
The International Geophysical Year programme for glaciology included the mounting of expeditions to observe the state of the ice on mountains in the tropics. In East Africa, Mount Kenya was visited by a party under Dr. Igor Loupekine, of the geology department at the Royal Technical College of East Africa, Nairobi; Kilimanjaro was visited by an expedition from Sheffield University, England; and Ruwenzori was covered by a team from Makerere College, the University College of East Africa, led by F. P. Henderson, lecturer in geology at the college. Five small expeditions visited Ruwenzori at six-monthly intervals, commencing in January, 1958. Markers were driven into the Speke and Elena glaciers, and their movement was later measured by theodolite. Pits were dug in the accumulation zone of the Elena glacier, and both glaciers were mapped on a large scale. General weather conditions were observed, and records were made of temperatures in and near the ice. Fluctuations in the volume of meltwater were recorded in one of the glacier streams. Photographs from surveyed points were taken of as many of the glaciers as possible. Comparison with earlier photographs shows that there has been a marked retreat of the glaciers since the visit of the Duke of Abruzzi in 1906, and that the rate of retreat seems to have increased during the past thirty years. Several glaciers which were photographed and named by Abruzzi have now disappeared entirely.
