fairly typical terrain on the West Ridge of South ...


Beginning at the basin between North and South Twin, ascend south to the ridge crest and follow it to a prominent notch below the summit. Many route options exist and the going is a steady class 3. One short class 4 down climb constitutes the crux of the route.

At the notch it should be obvious that continuing to follow the ridge crest will become class 4/low 5th, at this point traverse around to the south and follow gullies and/or a snowfield (seasonal) to the summit.

In general the rock is quite solid and the scrambling is among the best to be found in the Cascades. I believe this is considered one of the longest continuous scrambles in the range.


A rough climber's trail can be picked up around where a large pipe crosses the logging road, this can be followed to the aforementioned basin.


Some parties have reported bringing ropes and a light alpine rack, expect class 4 with some moderate exposure and plan accordingly.
