A pictograph is a drawing or painting that is created on a rock.It is not "carved" into the rock - that would be a "petroglyph."

Cueva de las Manos (Spanish for Cave of the Hands) is a series of caves in Argentina where ancient people painted on the walls starting over 9,000 years ago. The wall above is one of many that is covered with hand silhouettes. These silhouettes are thought to be made by the artist placing a hand on the wall and then blowing liquid pigment through a hollow bone to spray-paint the wall. The paintings in the caves are so significant that Cueva de las Manos, Patagonia is a UNESCO World Heritage Site.
