What is this pic?

Hints:
•I was discovered in 1976
•I was the subject of a 2000 movie starring Gary Sinise
•I was once believed to be evidence of alien life

Answer:
The original Mars face caused a sensation when images of a face-like hill produced by Viking 1 in 1976 were published across the world. The face, along with nearby pyramid-like structures, was believed by some to be an artificial structure constructed by alien life as a message to Earth. It was made the subject of a movie; Mission to Mars in 2000. The structure is a flat-topped hill, called a mesa, in which different rock types have eroded at different rates to produce the features of the face. Nice try with Keith Richards!
