In Back O' Beyond, there is myth in which you drive through a wall, fall, and get teleported to a random place. As the player enters the mountain wall in a vehicle, they will drive straight through the wall and drop down into what looks like, a blue background (most likely Blue Hell). The Player then spawns in a random location, losing their vehicle. It is unknown why this happens, but evidence suggest that the wall is only a texture not a solid, so the player can drive and then fall through it. It can be difficult to make this glitch work, but the results are astonishing.
Here, as shown on the photo on the bottom right, it is located just on the end of first the 'U' turn south on the map.
However, a game developer has said this: "The point is, if you get a 100 meters beneath level. (Z = -100.0 in technical terms, it's at Z = 0.0, inside a 3D space with XYZ.) You'll be teleported to the closest land, to prevent you from falling forever. This happens everywhere, but normally, you cannot go that deep without any glitches, bugs or modifications to the game itself. This is a type of variant of the blue hell glitch that just teleports you to the closet relevant location on the XYZ Axis. It is proven to exist.
