Cayoosh mountain
Located in the western Cayoosh Range, between Joffre Creek (Duffey Lake road) and the Birkenhead-Gates corridor. It is east of the Place Glacier peaks. Pronounced "Ki-oosh", "i" as in "I am a climber". "oosh" as in "whoosh, the sound of an avalanche". Cayoosh Mountain is a large partially glaciated peak. It is not the highest peak in the Cayoosh range, both Marriot Peak and Mount Seton are higher. Cayoosh Mountain can have large cornices which can be accidentally set off to come whooshing down on the eastern approaches. In general, once east of the divide, the snow becomes drier and more prone to avalanches, requiring more caution.

Name Notes: Cayoosh is a variation of Cayuse, the native name for Pony. One story is that a native was riding his horse from Mount Currie to Lillooet and the horse dropped dead at Cayoosh Creek. Once the creek had that name, the name Cayoosh was applied to the peak at the head of the creek. The range was then given the same name, but unfortunately the peak is not the highest in the range.

Near the head of the glacier, go north across a gap and immediately start climbing the east face of the summit block. Ascend 40-degree snow to gain the south ridge just south of the summit.
