The great Flood of Noah's day was a time of unthinkable geological upheaval, such that "the world that then was, being overflowed with water, perished" (II Peter 3:6). No flood in human history has rivaled its destructive magnitude.

Visitors often marvel at the beautiful columns of rock standing at places like Devil's Tower in Wyoming. There a mountain of rock rises from the ground in a series of regular, multi-sided columns, extending scores of feet into the air. Columns at the Giant's Causeway in Ireland and elsewhere seem so precise that fanciful legends have grown up around them.
