Here is A response, I'm certain there will be many:
In 1997, Mars was visited by a successful NASA orbiter called Mars Global Surveyor (MGS). With its high-resolution camera it was able to photograph the face site in far greater detail. This much-anticipated event put a lot of pressure on NASA - so much so that it actually had an adverse impact on the mission(2). However the photo was taken in 1998 and the mystery was solved.
The face was shown to be a natural feature. Specifically, the face is a mesa - an isolated, relatively flat-topped hill or mountain. Mesas are quite common on Mars and appear in many places on Earth as well.
Due to mission constraints the 1998 photo was taken on a angle and wasn't perfect quality. The conspiracy theorists weren't satisfied and wanted more proof. They got it in April 2001 when MGS was directly over the face site. The clearest photo yet was taken and left absolutely no doubt about the natural structure of this feature.
Really cool views of the 1976 "face" versus the 2001 photos here too, Simone:
