Cathedral rock in Sedona Arizona is one of the most photographed icons of the area. Sedona’s main attraction is its stunning array of red sandstone formations, the Red Rocks of Sedona. The formations appear to glow in brilliant orange and red when illuminated by the rising or setting sun. The Red Rocks form a breathtaking backdrop for everything from spiritual pursuits to the hundreds of hiking and mountain biking trails. The famous red rocks of Sedona are formed by a layer of rock known as the Schnebly Hill Formation. The Schnebly Hill Formation is a thick layer of red to orange-colored sandstone found only in the Sedona vicinity. The sandstone, a member of the Supai Group, was deposited during the Permian Period.
