Few places on Earth capture the imagination like the Grand Canyon. Stretching 277 miles, plunging over a mile deep, and layered with rock that chronicles nearly two billion years of Earth’s story, this natural wonder is both breathtaking and bewildering. To gaze across its vast chasm is to confront the immensity of geological time, where each band of colour is a page in the planet’s biography—written in stone. But how did this colossal canyon come to be? Was it carved by one catastrophic flood, slowly sculpted by the Colorado River, or shaped by an intricate interplay of forces across countless millennia?
The Grand Canyon’s Secrets takes listeners on a journey through science, history, and myth to answer these questions. Moving beyond tourist brochures, this book explores the canyon as a geological archive, a cultural landmark, and a still-active natural laboratory. Drawing on modern geology, palaeontology, and climate research, it reveals how ancient seas, shifting continents, volcanic upheavals, and relentless erosion combined to shape one of the greatest landscapes on Earth.
Inside, you will discover:
- Why the canyon’s rocks are unimaginably ancient, yet the canyon itself is surprisingly “young.”
- How uplift of the Colorado Plateau and millions of years of erosion—not a single flood—carved the canyon we see today.
- Why the Colorado River is considered a “misfit river,” and how its path reflects tectonic forces rather than simple chance.
- The role of side-stream erosion, weathering, and climate in widening the canyon’s immense profile.
- The mystery of the “Great Unconformity,” a billion-year gap in the rock record that leaves scientists debating what vanished chapter of Earth’s story is missing.
