Sand hills, that is.
In the afternoon heat, most critters are hanging out in the shade, but we see signs of them everywhere.
Lizard tracks (the line is from their dragging tails),
beetle tracks (These prints look like mini-bicycle tire tracks, don't they?)
and rabbit tracks.
These arcs look like a critter traveled in circles, but the effect is from wind swirling the grass blades through the sand.
The ants are out and busy, storing supplies for a rainy day (fat chance in the desert!) or maybe for the winter's chill.
