Upper Greasewood is a great little canyon, in an easy to access, yet remote feeling part of the Swell. Its short nature makes it a good beginner canyon with competent leadership. The canyon is not a slot, but more of a V-shaped canyon with many possible exits along the way. This canyon is like Upper Three, but without the potholes. The canyon is memorable to me, because of the large number of wild burro tracks we found in between rappels. The locals were clearly trying to find what during the hot summer months!

The canyon can hold quite a bit of water after recent rains but can be mostly dry after prolonged periods without precipitation. Between the two, my preference leans toward Upper Three Canyon, but since both are close together, it is easy to do them both in a weekend trip. (or even in a day for fast motivated groups)
