This first image on the left is a scene from John Carter, which shows a path within two ancient wall ruins leading to a massive stone structure, whereby this structure looks exactly the same as Shiprock Mountain, New Mexico. The main differences overall are that there are two walls in the movie, but just one wall remaining at Shiprock Mountain, and there is a large arch in the movie which no longer appears to be there.
These clear similarities between the scene and the real-life Shiprock Mountain suggest that Shiprock Mountain is actually the remains of an ancient structure, especially when also taking the following scenes into consideration.
