Mount Vancouver, North Buttress. A Japanese expedition made the first ascent of the north buttress of Mount Vancouver from the Hubbard Glacier. The first-ascent route (AAJ, 1950, p. 367) went up what might better be called the northwest ridge, though they called it the north ridge. The earlier route started from the Seward Glacier side. The two routes are completely distinct and meet only on the summit. Details are lacking.
