Cueva de las Manos

"Cueva de las Manos (Spanish for Cave of the Hands) is a cave located in the province of Santa Cruz, Argentina.
It is famous (and gets its name) for the paintings of hands, made by the indigenous inhabitants (possibly forefathers of the Tehuelches) some 9,000 years ago. The composition of the inks is mineral, so the age of the paintings was calculated from the remains of bone-made pipes used for spraying the paint on the wall blocked by the hand."
