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 (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]
