Every month this fall, KNAU has been taking you to places on the Colorado Plateau. They may be places you know, they may be places you've only heard of. It's a series we call Land Lines and today we're visiting Monument Valley. People come from all over the world to see this valley, one of the most evocative landscapes in the southwest. But at least one rock feature doesn't quite fit the mold of the mesas and buttes. In today's Land Lines, Rose Houk and Michael Collier explore the origins of El Capitan.
S.P. Crater--Today on Land Lines, Michael Collier and Rose Houk take us to S.P. Crater near Flagstaff. Early cowboys gave this perfectly shaped cinder cone its initials--whose shape reminded them of a ……chamber pot.
Climbing the steep slopes of S.P. Crater, you take one step forward and two steps back in the loose black cinders. This beautifully symmetric cone, about thirty miles north of Flagstaff, reminded local cowboys a century ago of the shape of a chamber pot, thus the initials S.P. As the old wranglers used to say, Volcanoes happen.
