Upper Greasewood is a great little canyon, in a 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.
