"Organ Rock Formation The Organ Rock Formation or Organ Rock Shale is a formation within the late Pennsylvanian to early Permian Cutler Group and is deposited across southeastern Utah, northwestern New Mexico, and northeastern Arizona. This formation notably outcrops around Canyonlands National Park, Natural Bridges National Monument, and Monument Valley. The age of the Organ Rock is constrained to the latter half of the Cisuralian Epoch by age dates from overlying and underlying formations. Important early terrestrial vertebrate fossils have been recovered from this formation in northern Arizona, southern Utah, and northern New Mexico. These include the iconic Permian terrestrial"

Contrary to the implication of the name, the cliffs are not a single set of rock formations, but actually a geological formation that manifests itself in multiple sets of rock formations. The cliffs form a large number of unique rock formations, many of which are protected by either the Bryce Canyon National Park or the Cedar Breaks National Monument. Most of the other formations are located within the Dixie National Forest. Geologically the"
