This is a great page. My only suggestion might be to change the name of the route since it might cause confusion.
Zion already has a well known canyon named Checkerboard Canyon, but it north of the canyon you are referring to as Checkerboard Canyon.
It might be a good idea to change the name route page for this reason, since it might cause some confusion, but it is up to you.
What should I call the canyon? I have to think about it.
Changed it to "Checkerboard Mesa Canyon".
