A desert spiny lizard disguised as a tree lizard (these guys are usually found on the ground);
An agave stalk that seems to be part corkscrew;
And a beautiful diamondback on one of our main trails. He (or she) could not at first decide whether to cross the path. Eventually, the snake made the sensible decision to turn back and disappear into the dirt, rocks, and desert plants, where it no doubt lay in wait for its next meal. I am mesmerized when I watch these amazing animals flow along the ground, so graceful and deadly.
