Inscription. Click to hear the inscription.

Erosion produces unusual shapes on the landscape. As the protective Kayenta Formation layers erode from the ridge before you, the softer Wingate Formation beneath it is exposed and responds in a unique way. Early visitors throught these shapes looked like man-made structures called coke ovens.

[Inset photos caption reads]
The Kayenta Formation is resistant to erosion and in the past shielded the underlying Wingate Formation (left). Over time the Kayenta eroded exposing the Wingate to the forces of erosion (above). As the Wingate eroded it formed these dome shapes.

[Background photo reads]
Coke ovens were used to transform coal into coke, a fuel that produces little or no gas when burned.
