Pine Creek Canyon is a popular technical canyoneering route in Zion's National Park. It's a great canyon with multiple rappels, beautiful hiking and often times swimming. The 4th rappel in the canyon, is into a chamber, under double arches, known as 'The Cathedral'. To log this as a find, take a picture in the Cathedral (which you'll likely want anyway), or email me with some other proof that you completed the canyon. The canyon is much too narrow to get exact coordinates to the Cathedral, so the coordinates are to the head of the canyon. From there, just head down canyon. You can't miss the Cathedral.

Warning: Although this is one of the easier and more popular canyons in Zion's, there are many people who get into the canyon unprepared and end up having to get rescued. Please make sure you are well prepared to descend the canyon. I can direct you to multiple websites with good route descriptions if you want to better prepare. Just drop me an email with any questions.
