The San Francisco Volcanic
Field of Northern Arizona

Including SP Crater, Colton Crater, Merriam Crater,
Black Bottom Crater, Medicine Valley, Walker Lake,
Red. Mt., Cinder Hills, Cinder Basin, and other places
The San Francisco Volcanic Field of northern Arizona includes around
600 dormant or extinct volcanos. In the greater Flagstaff region, ancient volcanic
activity produced such large, well-known mountains as the San Francisco Peaks,
Kendrick Mountain and of course Sunset Crater. However, many lesser-known volcanos,
or cinder cones as they're often called, are also worth seeing including, but certainly not
limited to, SP Crater, Colton Crater, Merriam Crater, Red Mt., Black Bottom Crater and
a couple of nice craters flaking Medicine Valley. The dark, partially forested Cinder
Hills and Cinder Basin on the "back side" of Sunset Crater are also uniquely beautiful.

Drone Photos
I have climbed to the rims of both SP and Colton Craters
with a regular camera. However, to fully appreciate these cinder
cones and get a true sense that they are in fact ancient volcanos
you must get an aerial perspective. Fortunately, a friend
lent me a very nice drone so I was able to do just that.
