Schnebly Hill Formation
The Schnebly Hill Formation is a section of red bed deposits found at the Colorado Plateau, near Sedona, Arizona. It is a dark red sandstone, from 800 feet (240 m) to 1,000 feet (300 m) thick. It lies between Coconino Sandstone and the older Hermit Formation. It is near the Supai Group.
The source of the name "Schnebly" is Sedona Schnebly, after whom the city of Sedona, Arizona, was named.
Geology
The formation traces to the Permian Age.
The formation is the most prominent layer of the red rocks of the Sedona area due the presence of hematite – iron-oxide, frankly, rust – giving the sandstone a red color. The Schnebly Hill Sandstone formation comprises three sections:
- the Bell Rock member,
- the Fort Apache member, and
- the Sycamore Pass member.
