Meteor Crater: A Geological Marvel in Arizona

The Impact

Meteor Crater, also known as Barringer Crater, is a testament to the cosmic forces that have shaped our planet. Approximately 50,000 years ago, a nickel-iron meteorite hurtled through Earth’s atmosphere and collided with the Colorado Plateau. The impact released energy equivalent to 10 megatons of TNT, vaporizing nearly half of the meteorite. The result? A 3,900-foot-wide and 560-foot-deep crater—an ancient scar etched into the desert landscape.

Unique Features

Squared-Off Rim

The crater’s rim rises 148 feet above the surrounding plains. Its squared-off shape is a consequence of existing regional jointing in the rock layers. This distinctive outline sets Meteor Crater apart from other impact sites.

Layers of Rubble

Within the crater, layers of rubble—690–790 feet thick—rest atop the bedrock. These remnants tell the story of the cataclysmic event that shaped this geological marvel.

High-Pressure Minerals

Geologists study Meteor Crater for its unique features, including the presence of high-pressure minerals formed during the impact. These minerals provide valuable insights into the extreme conditions created by the meteorite’s collision.

National Natural Landmark

Designated a National Natural Landmark in November 1967, Meteor Crater remains remarkably well-preserved due to the arid climate. It invites us to contemplate cosmic collisions, the forces that shaped our planet, and the silent stories hidden within its ancient walls.
