In the early 1930s there were several visits to the moorlands around Mount Kenya, with fewer as far as the peaks. Raymond Hook and Humphrey Slade ascended to map the mountain, and stocked several of the streams with trout. By 1938 there had been several more ascents of Nelion. In February, Miss C Carroll and Mtu Muthara became the first woman and African respectively to ascend Nelion, in an expedition with Noel Symington, author of The Night Climbers of Cambridge, and on 5 March Miss Una Cameron became the first woman to ascend Batian.
