Austrian geologist Eduard Suess summarized in 1891 the results of an expedition to Lake Rudolf by Count Samuel Teleki and suggested that the valleys and mountains crossing Africa were the results of periodic tectonic movements. ‘The Great Rift Valley: some associated fractions are marked by broken lines’, from GREGORY 1920.
