 Did some unknown prehistoric civilization utilize such massive unidentified machinery as this huge "what's it?" said by an informant of Brad and Sherry Hansen Steiger to have been excavated from a great depth circa 1990-91 on government property during work on a secret project? According to the Steigers' anonymous informant, this incredible, gargantuan artifact--see how it dwarfs the dumpster on its left side--and five or six exactly like it were unearthed, then all reburied in the same area. The surface of the mysterious apparatus is covered with peculiar hieroglyphs. This photo is taken from UFOs Are Here! by Brad Steiger and Sherry Hansen Steiger.
