Love this picture - and it set me thinking: I have always wondered about these great formations in America; I have read how they are the sedimentary layers of the beds of ancient oceans and how, after being laid down over millions of years, they have been eroded away by the weather over further millions of years. However, what if it wasn't the weather ? I was reading the other day on the BBC website a piece about extra-terrestial activity and how, if people from other worlds had visited our planet in the ancient past, what tell-tale signs we could look for. It went on to say that rather than hope to find alien artifacts, our best bet would be to look for evidence of industrial activity - such as mining. Just seeing your picture here switched on a light-bulb in my head: supposing these majestic formations weren't created through erosion caused by weather, but were the result of open-cast mining on a massively wide scale ? The thought is intriguing, isn't it ?!
Haha you definitely have imagination ! I think that those big rock cliffs and shapes used to be under the sea level, I've read that there was a sea around here in Colorado, so I guess it got kind of eroded and consumed by the water, randomly building mountains and holes and.. stuff I'm actually not comfortable enough with English to have a discussion about this.. I wish I had the level !
