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 upwards, to the surface of a New York state forest. With illustrations and simple diagrams of the botanical and biological evolution that occurred around this prehistoric rock, Bruce Hiscock has again made natural science easy to understand for young readers.
