Take a look for yourself.
Could Erich von Däniken have been right after all?
On CBC's As It Happens last night they talked about a fascinating, natural feature in southern Alberta (that may rival Mount Rushmore ??) that can be seen with Google Earth. One description of this rock face is titled AZTEC with an IPOD. If you want to see this image (and perhaps submit a name for the feature) just click on the image of the rock face at the following link and it will take you directly to the Google Earth view.
Spoilers-- The IPOD earpiece is a well-site and access road. Also what
appear as the raised areas are actual the shadows in the depression.
