S-P-Crater-Arizona-Infrared.jpg
S-P Crater, Arizona (Infrared).  Framed here by a gaunt-but-graceful juniper tree, this well-formed cinder cone north of Flagstaff is estimated to be around 60,000 years old (i.e., very young by geologic standards).  It is part of northern Arizona’s San Francisco Volcanic Field, a hotspot that contains over 600 volcanic peaks and vents.<br />

Tech info: Nikon D3200 camera (modified for infrared with 590nm filter), Nikon 18-140mm lens at 18mm, 1/320 sec. at f11, ISO 200.<br />
