Red Mountain is one of several hundred cinder cones within a swath of volcanic landscape that extends 50 miles eastward from Williams, Arizona, through Flagstaff to the canyon of the Little Colorado River. Red Mountain is unusual in that its internal structure is exposed. The amphitheater of Red Mountain has many "hoodoos", rather bizarre landforms that are especially common in the western part of the exposed amphitheater of the volcano. It is a wonderful easy hike that leads to the innards of this volcano, revealing wonderful photographic opportunities. The day started out cloudy, but then for about 20 minutes, the sun broke through the clouds illuminating the red hoodoos. Eventually a thunderstorm developed overhead and ended the photoshoot early, but for a brief time, it was like being in a natural cathedral.
