Desert Spiny Lizard

Desert Spiny Lizard -- Pipe Spring National Monument, AZ
Canon EOS Rebel T5i, EF 100-400mm f/4.5-5.6L IS II USM, 1/1600s, f/5.6, ISO: 1600

I saw this little guy on the wall at the Pipe Spring Visitor Center.  I must have made ten trips to use their water fountain.  It was cold and delicious.  This lizard was hanging out nearby.  Ain't he cute?
