Spider holes--filled with hundreds of daddy longlegs. Creepy
Trying not to get wet. Good luck.
A boulder wedged in the canyon
A wall of beautiful ferns. Doesn't look like southern Arizona, does it?
Another type of critter you might meet on your journey. Be careful, there are lots of these guys out there

Watch out for those huge waterbugs!

The waterbugs got another poor soul
