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.[2] It is near the Supai Group.[3]
The source of the name "Schnebly" is Sedona Schnebly, after whom the city of Sedona, Arizona, was named.[4]
Geology
The formation traces to the Permian Age.[5][6]
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.[7]
