What's everybodys take on them? I know alot people that would like to believe they were built by aliens and i viewed some older pics of them and at the time they did appear to look like they were constructed, But to me they just look like very large sand dunes like the ones we have on earth and i think that the facial features are more attributed to the wind blowing over a period of years instead of aliens building them
It's been pretty well established that these are formations that play tricks on the mind. They were created by "wind and time" - just like we have many similar examples on Earth of Rocks that took on "Specific Forms" - From a rock formation that looks like it could be an Elephant - to many number of cliffs that have facial features. Even the "face of a man" when we look at the Moon at just the right time.
There is also what I think I remember being the "Gastalt Theory" (sp?) - where he show that with various shapes and such our MIND sees things that are not there. Like when you take a several rows and collums of squares, you'll see circles between the four corners in the gap. Optical illussion, in that the circles are not really there.
Several people actually went and got the topographic data and converted them to DEMS and processed the 'raw' data in programs like BRYCE and Vita Pro and 3D Max. When the light is 'right' you see a face. When the light source changes it's not longer a face but a rubble of rocks, stones, dust.
