Has anyone heard of these? The acronym stands for Out Of Place Artifacts, and there are some doozies. For instance, a geode found in the Cosa Mts. of California containing an ancient device that could only be identified as a "sparkplug." Or a ship sunk in the Aegean Sea circa 1 B.C. that carried an analog computing device, replete with differential gears. Wild stuff.
