Lenox Crater

Lenox Crater is a cinder cone in the San Francisco Volcanic Field, recognizable by its steep sides covered in reddish volcanic rock and dark cinders. The cone rises distinctly from the surrounding landscape, showing the raw materials thrown out during the eruption that formed it.

The cinder cone formed roughly 1,000 years ago when a volcanic eruption scattered ash and rock fragments across the region. This eruption was one of many events that shaped the San Francisco Volcanic Field over centuries.

The crater stands as a natural laboratory for geologists and researchers studying volcanic formations within the Colorado Plateau region.

You can reach the crater by following a marked hiking trail that climbs to the summit and reveals views across the volcanic landscape. The ascent is steep but the hike remains short and manageable for most visitors.

The cone ranks as the second most prominent formation in Sunset Crater Volcano National Monument, distinguished by a rise of roughly 55 meters. This height makes it a noticeable landmark against the relatively flat surrounding terrain.
