West Ridge

From Lambert Col via the upper Frances Glacier and Main Divide To avoid the gut directly below Lambert Col, sidle south onto a snow shoulder then sidle northeast back to the Frances Glacier. At 2000m, a significant crevasse can be challenging to cross. Continue up to Malcolm Col then SE, where there are smaller crevasses to the Main Divide under pt 2283m. Follow the Divide along with some easy rockclimbing involved near pt 2276m. From a patch of gravel low on the SW ridge, climb diagonally across the western face towards the NW arete. An easy walk on the ridge completes the climb.
