Standing Rock in Canyon del Muerto. An archaeological site dating between AD 1100 and 1300 is visible on the lower bench of Standing Rock, closest to the viewer. A circular arrangement of plants in a Navajo field, visible to the left of the rock, suggests that it was an orchard or, less likely, that a center-pivot irrigation system was used there.
