Cueva de las Manos

There's a cave thing in the province of Santa Cruz, Argentina, that's called the Cueva de las Manos. "Manos", in Spanish, means "hands". Basically, it's famous for its artistic-looking cave paintings/markings featuring tons of profiles of hands. Not sure why, but it sounds like worth a look. Definitely more interesting than the boring old Spanish-like writing here.

Also, the valley that the cave is located in is beautiful.
