Upper Greasewood is a great little canyon, in an easy to access, yet remote feeling part of the Swell. It's short nature make it a good beginner canyon. The canyon is not a slot, but more of a V-shaped canyon with many possible exits along the way. This canyon is similar to Upper Three, but without the potholes.
