| | |   Trinitite. When the first atomic bomb was set off, the "trinity" test, it melted the desert, forming a 600 yard diameter crater with a crust of greenish glass (glass is molten sand).  This glassy material, which has come to be known as trinitite, was quite radioactive at first, but has by now died down to a fairly low level.  It's removal from the site is forbidden, but a good bit is in circulation (though so is a good bit of fake trinitite as well).
