Six to seven million years ago, a volcanic eruption from the Jemez volcanic field left layers of ash, pumice and tuff. Pyroclastic flows added to the layers. Today, harder cap rocks have protected, to some extent, softer rocks below, resulting in fantastic tent-shaped formations.
Trails bring visitors into the formation area.
One of the trails follows a slot canyon mere feet wide.
When the trail emerges from the slot canyon it leads hikers up a steep path to the ridge above the formations.
From there, views reveal the surrounding lands and the tops of the fantastic formations that give this area its name.
