The Great Man-Made Crater, or 地狱洞 is a mysterious large crater located about 60 km west of the town of Pogoth, Chesad province. The crater has a diameter of 1,500 meters, it is about 180 meters deep and is surrounded by a rocky rim that rises above the surrounding plain to a height of 50 meters. The crater's existence is confirmed only by a handful of photos taken by a commercial drone owned by a civilian and then posted in the RockWatchers online geology forum. There are several theories as to the true origins of the crater from geology enthusiasts, researchers, conspiracy theorists and overseas government opponents. After the appearance of the photos online, local government officials simply commented that such a crater does not exist and the pictures were simply doctored to create confusion.
