Elepahnt feet is located on US-160 about 100 miles North of Flagstaff, Arizona, in the Navajo Reservation.
I intentionally left the vehicle in the picture to better illustrate the size of these rock formations.

"Plenty of vehicles stop on the side of the road near the pair of lonely sandstone towers jutting out from the flatlands east of Navajo Nation. To everyone who sees these formations, they look exactly like their name: Elephant Feet. There is no visitor center, but that's part of the beauty of these pachyderm formations — you can walk right up and touch the "toes" of these rocks."
