Dave Noden has added an excellent left-to-right traverse extension to The Cost of Living at Gallt yr Ogof in the Ogwen Valley. This little visited 5+ is a contender for the best of its grade in North Wales. It was first climbed by Ray Wood in the early noughties; details of it can be found on page 146 of the 2004 NWB guide.
Dave’s new extension starts on two sidepulls just left of the aręte to the left of the main aręte. Positive crimps and a long cross and drop down move gains the starting hold of the original problem.
