The Geologic Oddity in Arizona; The Largest Kimberlite Pipe in the World

Within the state of Arizona are a number of fascinating geologic features. One of these features is a little known formation in Apache County which contains abundant gem grade peridot crystals. Here, 25 million years ago, a massive volcanic eruption occurred. This eruption deposited what is now recognized as the largest single kimberlite pipe on the planet. Kimberlite pipes are traditionally associated with diamonds, yet this one was unusual. This video will discuss this geologic oddity.
