Elaborate ancient Native American petroglyphs of the Basketmaker Culture of about 2000 years ago chipped into the black desert varnish of a cliff face in the Bears Ears National Monument in Utah.  Plants are only rarely pictured in their rock art, but these petroglyphs are thought to represent the yucca plant, which was used to make soap, rope, sandals, medicine and food.
