I dropped down around the east side. It was 4th class down the north ridge and east face, but very loose. There may be a better way closer to the ridge itself. From there, it was more loose class 3-4 down the north side of the east-going spur ridge, then a boulder slog up Farquhar. Trip report.
Penelope and I scrambled up the "Bob Burd Staircase" (our name) on the SW Face on June 20, 2012. We found the route (which might have had FA by Bob Burd in 2010) to be a very nice 3rd class scramble on excellent rock. RJ Secor calls his Mantle, Lilley, Secor 1972 Northwest Ridge a NICE CLIMB, I would call the "Burd Route" a BETTER one. The route climbs series of clean rock steps in the central couloir (the most obvious one) on the SW face and ends directly on the summit of the peak. We descended the South Ridge, a good and obvious descent route. Great if strenuous outing in a wonderful, remote setting.
