She then spent an idyllic two months (January-February 1929) based in Urumandi Hut on Mount Kenya (see Mountaineering on Mount Kenya), in the giant heather and parkland zone, some of the time with two porters and some alone, exploring the mountain and valleys, bathing naked in the rock-pools below the Nithi Falls, befriending the birds and small animals, collecting flowers and seeds, sketching the flora, and meditating first principles. While up at the peaks she witnessed the third ascent of Mount Kenya, by Eric Shipton, Percy Wyn-Harris and Gustav Sommerfelt (January 1929), who next day took her on a scramble around the south-face glaciers. She thanked them on their return to Urumandi Hut with perfectly mixed cocktails. In her last weeks on the mountain she and the porters saved the alpine hut from a forest fire after a day-long struggle. Suffering toothache a few days later, rather than cut short her stay and return to Nairobi, Vivienne pulled out the tooth herself in an operation that took three hours and forty minutes, using first fishing-wire and gravity, then pliers from her tool kit.
