Chapter I: Introduction

A pack-burro camping trip in an unexplored region of the high Sierras results in a series of adventures for three boys in the late teens, a young Geological Survey man and the old prospector who guides them.

They meet bears and catch rainbow trout, are carried to fight fire by the Forest Service Air Patrol, and trail the incendiaries through a labyrinthian limestone cave. They ride in a lumber camp rodeo and experience earthquakes and avalanches. And in the glacier-gouged canyons, the giant Sequoias, and sulphur springs, they trace the story of the geological formation of the earth, and its evolution from the days of dinosaurs.
