We took a guided Jeep tour in Canyon de Chelly (pronounced "De Shay"). The tour company was Canyon de Chelly Tours and I highly recommend their guides. These ruins are called Antelope House and is named after the rock art painted nearby.
Our Navaho Guide, Daniel, told us the colorful antelope artwork was added to the cliffs sometime around the 1830's by a Navaho artist named Little Lamb. The other art found here is much older and was left by the Anasazi people. The Swastika shown in this photo is actually an ancient native American symbol which could mean four seasons, four directions or an indicator of migrations. This area was the last stop on the The North Rim tour and is located at the point where Canyon del Muerto and Black Rock Canyon come together.
