Cave Paintings

Photo: Horse paintings in  Chauvet Cave
Careful preservation makes analysis possible. Cool and damp, Chauvet Cave's steady interior climate—56 degrees Fahrenheit (13.3 degrees Celsius), with 99 percent humidity year-round—contributes to the French cave's remarkable state of preservation. The large, complex Panel of Horses in Hillaire Chamber receives attention from researchers.
