This photo was taken by my uncle while visiting Mexico in January. It is one of 600+ pictures they took while there. This one stood out...just a bit. This is taken at the Mayan Ruins of Tulum. What I need help with is verifying the integrity of the digital shot, and/or identifying the strange "UFO" like blob in the the left hand corner. (I am in firm belief that from my investigation of the image that this is not a natural object. Perhaps a plane, but that is very unlikely given its shape.) Post on friends.
