Anomaly Hunters Spot 'Doorway' on Mars

The intriguing oddity was photographed by the space agency's Curiosity rover this past Saturday as the vehicle was continuing its mission exploring the Red Planet. The image in question shows a rocky hillside that initially appears fairly pedestrian until one looks closer and sees what appears to be a doorway seemingly carved into the landscape and leading into a hallway with walls sporting smooth sides.
