|From the Hunter Valley||1||
A difficult bush bash from the Hunter Valley about two km downstream from Paddock Flat leads to the western slopes and provides access to the summit.
Jack Aitken, Jack Gillespie, Alma Mitchell, M.A.Sutherland, January 1943
From upper valley climb snow slopes to reach the Calvin-Wyn Irwin col, then follow the ridge toward Wynn Irwin. Pinnacles and the very narrow final step between east and main peak can be avoided by descending approximately 100m onto the north face then sideling along to gin the eastern edge of the north face which is followed easily to the top.
