the hitherto unknown highland regions of Mt. Kenya

Gregory's important exploration expedition in the hitherto unknown highland regions of Mt. Kenya.

In 1892 Gregory was seconded as naturalist to a large expedition to British East Africa; when this collapsed, he set out on his own with a party of forty Africans. In five months, he completed scientific observations in fields ranging from structural geology and physical geography to anthropology, and from mountaineering and glacial geology to the malarial parasites. His major success was the study of the volcanic rocks and structural features of what he termed the 'Great Rift Valley'.
