SP Crater

The cinder cone volcano with a less than complimentary name. 

SP Crater gets overlooked for a few reasons- the neighboring volcano, Sunset Crater, is a bit more picturesque with its forest setting, and has national park status. SP Crater is off by itself on private ranchland, but the landowners permit visitors to check out this perfect example of a cinder cone and its nearly six-mile lava flow. 

The crater was eloquently named by 1880s rancher and landowner of the cinder cone C.J Babbit, after what he felt the view from the top resembled the most- a shit pot. Unlike Sunset Crater, you can climb to the top of SP Crater, and if you’re sure-footed, you can even drop down inside of it.

Volcanologists estimate SP Crater is 65,000 years old.
