The Big RockPaperback, 1 December 1999

This is the story of a very old rock.

The "'big rock" is a granite boulder that began as molten rock millions of years ago. Through the ages, the mountains above it wore down, the ocean flooded the region, and then new mountains heaved the rock upward, to the surface of a New York State forest.

Even though the dinosaurs and other living things have come and gone, the rock remains as a survivor of the Ice Age and silent witness to the earth's continuing evolution. Once you know its story, you will never again overlook another rock like this one.
