SP Crater
San Francisco Volcanic Field, Flagstaff
The story of SP Crater’s name begins with Northern Arizona rancher C.J. Babbitt. Sometime in the late 19th century, the story goes, Babbitt climbed a cinder cone volcano north of Flagstaff and observed its dark-colored lava flow extending to the north. It looked, he thought, like a chamber pot that had been spilled.
