The Sedona area was at sea bottom 330 million years ago, and the shells of sea creatures formed a layer of limestone that underlies the area today, called the Redwall limestone because of its color, the result of iron oxide deposited in the rocks by water in later eras. Twenty-five (million to) 15 million years ago, the continental crust was stretched, and the rocks in the South Mountains were pulled out from underneath that area to the northeast, underneath Fountain Hills, and brought up to the surface, said ASU geologist Steve Reynolds, an expert on bedrock features in metro Phoenix.
