Fortress, Paine Group. In January Keith Myhill, Phil Burke and Mick Horlov climbed very nearly to the top of the east face of the Fortress. Two earlier attempts had been beaten off by bad weather. The final climb lasted for 13 days. The 6000-foot-high climb was of extreme difficulty. Burke froze his hands and so when the weather turned bad, the climbers did not do the final rope-length up summit terraces. More details will be found in Mountain 66.
