Origami - the ancient Eastern art of folding paper to resemble something except a piece of crumbled paper! However, when origami was introduced to the Western world it got a lukewarm welcome - who's got time to sit down and fold paper? The origami craze did not take off until perforated toiletpaper was invented (or so I've been told). 
Here's your assignment if you choose to accept it:
Print the attached picture.
Cut off any extra paper outside the square.
Start folding - you're making a flapping bird.
Good luck and have fun!
It should be fairly easy to get to the cache except for the last part that involves minor bushwhacking. Watch out for muggles!
Don't forget to write down the code for Code #9 to be able to solve for 'Tecolote "Puzzle" Canyon #20 - Finale!' or you'll have to go back again.
It's bad caching karma to rip papers from the log - bring a writing instrument and a piece of paper with you.
Fine Print:
I will not confirm, check, verify, look at, clarify, corroborate, substantiate, authenticate, validate, or give personal hints until all 20 puzzles have been solved. It's only fair since there are some hardcore puzzle solvers that are toiling with these puzzles. However, if you e-mail me where you are stuck and the puzzle has not been solved for an extended period of time, I can add hint(s) to the listing for everybody to see. Feel free to send me an e-mail whenever you are stuck, but don't expect a personal reply until all 20 are solved.
Instead of writing notes in the cache log as a as a way to communicate with each other, you can discuss the puzzles in this thread in the forums, but no blatant hints or spoilers please. Keep that off-line!
