Salt domes, naturally-occurring geological formations, have attracted dramatic transformations. Though they exist in other parts of the USA, they are mostly found in the Gulf region of the southeast, where hundreds of them are scattered in a great arc from Texas to Louisiana. Many linger unmolested, deep underground. Others approach the surface (or the surface erodes down to them), revealing themselves and the opportunities they offer. Others have been sought out, detected by subsurface imaging technologies, and been bored and excavated remotely, while remaining thousands of feet below the surface.
