Notable achievements by the Lairig Club during this era include: Patey and Gordon Leslie's ascent of Douglas-Gibson Gully on Lochnagar in 1950, the first winter grade V climb in Scotland. In June 1952 eight club members made an en masse first summer ascent of Parallel Gully B, the last of the major gullies to be climbed on Lochnagar. Another Lairig meet in the December of that year saw the first ascent of The Scorpion another early grade V on Carn Etchachan by Patey, Taylor, Grassick and Nicol. First winter ascents of Mitre Ridge on Beinn a' Bhuird (V,6) by Brooker and Patey and Eagle Ridge (VI,6) on Lochnagar in four and a half hours by Brooker, Patey and Taylor proved that the Lairig really were at the head of their game. Even today with modern equipment and techniques these routes are still well respected and serious lines. Other than the first ascent of Raven's Gully in Glencoe by Hamish MacInnes and Chris Bonington in 1953 all the grade V routes in Scotland were confined to the Lairig's stomping ground of the Eastern Cairngorms in the early 1950s. Lairig members Patey and Nicol teamed up with Hamish MacInnes to climb the first grade V on Ben Nevis, in the form of the much prized first ascent of Zero Gully.
