This massive piece of machinery was one of six excavated around 1990 from a great depth on secret government property in the United States, then promptly reburied in the same area. The enormous device dwarfs the dumpster and the crane shown to its left. Nobody has been able to definitively identify this mind-boggling machinery. This photo is from a book titled, "The Rainbow Conspiracy" by Brad Steiger and Sherry Hansen Steiger.

Towers of Silence -- Zoroastrians believe the body is impure and shouldn't pollute the earth after death through burial or cremation. Instead, the deceased are brought to a ceremonial "tower of silence", usually located on an elevated mountain plateau, and left exposed to the animals and elements. When the bones have been dried and bleached by the sun, they are gathered and dissolved in lime. (Credit: Wikimedia commons user Yosemite)
