FATMAP difficulty grade
Hidden Knoll is a prominence just beneath Current Creek Bench.
The Halfpipe is a straightforward, low-angle route off the south side of Hidden Knoll.
It follows a creek bed, so be aware that you are in a bit of a terrain trap if anything above you were to slide.
However, avalanche danger in this area is often fairly low (but not always!).
