The Junction Overlook at Canyon de Chelly in northeast Arizona is the third overlook along the south rim drive. The view is toward the junction of the Canyon Del Muerto arm to the north and the Canyon de Chelly arm to the south.
The interpretive signs at the view point emphasize the geology of the canyon. The Shinarump Conglomerate on the surface was deposited 170 million years ago and the de Chelly sandstone that forms the sheer walls has been here for 230 million years. The floor layer is named the Supai Formation from 280 million years ago.
