I've wanted to do that last rappel ever since I laid eyes on it a few years back when I first started hiking WCC and today was finally the day. I went with a group of 7 who I mostly knew from the climbing gym and we set out that chilly morning and dropped into Sundance to perform some down climbing, rock hopping, stemming, swimming, wading, and a few rappels to get to that amazingly SWEET 180ft rappel. Only 3 of us wore wetsuits and the others just suffered thru the chilly water and shaded narrows while waiting for their turn to rappel... The potential keepers near the end were full to the brim and most of the canyon is fairly straight forward and not too bad to traverse thru, just make sure to only bring people who are experienced at rappelling, down climbing, swimming in cold pools, and can handle such a high final rappel.
