My buddy and I completed this canyon yesterday (9/17/16). It was my first weekend canyoneering, and my partner was the one showing me the sport. Unfortunately, on the 3rd rappel, he pulled his shoulder out grabbing onto a rock(Not a great place to be injured). Fortunately, we knew enough about rock climbing/rescue to get him out of there safely and to the ER. We had two ropes but also left two ropes because I managed to get them stuck in a state of panic and uncertainty.( I wasn't familiar with clean anchor systems) A lot was learned, and will wait to return until canyoneering knowledge is better. If you happen to read this and retrieve the ropes anytime soon, I would greatly appreciate the return and pay for any sort of shipping with a reward.
