Over the alpine tundra, the land above the trees on a high mountaintop, hangs an enormous rock. Below the rock, a pocket gopher tunnels underground, storing away seeds for winter. The rabbit-like pika begins her harvest of grass and wildflowers. And a boy named Johnny rolls over in his tent as he wakes up for the day. Suddenly, the great rock slips...and the alpine tundra is about to be changed forever.
