Ancient origins

The Grand Canyon isn’t just old—it’s millions of years older than previously thought. Some rock layers at the bottom date back 1.8 billion years, nearly half the age of Earth itself. While the canyon itself is around 5 to 6 million years old, recent studies suggest parts of it began forming 70 million years ago—during the dinosaur era.

Once an ocean floor

Long before it was a canyon, this region sat beneath an ancient sea. The Kaibab Limestone, the canyon’s top layer, formed from marine fossils left behind as the waters receded 270 million years ago. The presence of coral, shellfish, and even shark fossils proves the area was once home to a thriving ocean ecosystem.

Carved by more than water

While the Colorado River played a huge role in shaping the canyon, other forces were at work. Volcanic activity, tectonic uplift, and even landslides helped carve out its immense depths. Lava flows from nearby volcanoes poured into the canyon, creating layers of rock that tell the story of violent geological change.

The earliest human inhabitants

Humans have lived near the Grand Canyon for at least 12,000 years. The earliest known inhabitants were Paleo-Indians, who left behind stone tools and spear points. Later, the Ancestral Puebloans built cliff dwellings and left behind intricate pottery, proving that this seemingly inhospitable land was once home to thriving communities.

Named a national monument

Hidden caves

John Wesley Powell led the first recorded expedition through the Grand Canyon in 1869. With one arm lost in the Civil War, he braved the Colorado River’s treacherous rapids in wooden boats. His journey mapped the canyon’s uncharted territory, proving it wasn’t an impassable wasteland but a geological treasure trove.

Forgotten civilizations?

In the 1930s, explorer Emery Kolb uncovered a sealed cave in the canyon containing ancient artifacts and human remains. Some speculated it belonged to a lost civilization, but archaeologists determined it was a prehistoric Native American site. The canyon still holds thousands of undiscovered archaeological sites, adding to its mystery and historical significance.
