Arête W
From Brewster refuge follow the path that goes toward Mount Amstrong then halfway along traverse the slopes on the left to reach the glacier. Cairned but not so obvious at night.
Cross the glacier in its entirety then follow the west ridge to the summit.
Gear to set up an abalakov, in case the slopes are iced up.
Many possible alternatives, of traverses.
Depending on the season, snow-covered or rocky ridge, somewhat mixed.
Mick Bowie, H.G. Courtney, 1934.
