  • "Back in the early nineteenth century . . . geologists in Europe and the Great Lakes region of North America began to take note of so-called erratic boulders, which were composed very differently from the local bedrock on which they rested. Monoliths of granite sat, illogically, on limestone; slabs of schist, improbably, on sandstone. The most reasonable interpretation of these foreign rocks, in the context of the contemporary understanding of Earth's history, was that they had been washed in by the waters of the Great Flood of Noah. Geologists called such flotsam "drift," and an early version of the geologic time scale included a period known as the Antediluvian--that is, "before the deluge.""
