“Think of layers of wax that are just squeezed,” Mr. Horenstein said. “Even when it’s weathered, you can see all those convolutions.” The marvels continued, as a granitic substance filled in the cracks after the deformation, creating delicate traceries. Retreating glacial ice finally gave the whole thing a terrific polish that endures to this day.
