This is a Cliff Chipmunk. I photographed him at the campsite at Chiricahua National Monument. Not sure what it was at first because of the large fluffy tail, i sadly misnamed it a squirrel because there are some unique ones in the area. However the ranger and I delved into a book or two and discovered that it was a neat chipmunk. You never know what you will see out your door when your door is in lots of places.
