Climbs the buttress left of West Coast Boomer. Approach by crossing the corrie floor until it is possible to angle back left across the large snow field beneath the top wall. Begin 10m left of the corner of WCB and climb a turfy groove, turning terraces by the line of least resistance bearing left then right, reaching the spur on the left of WCB after four pitches. Follow this as the angle eases to reach the top of Tom na Gruagaich.
