Millions today go to Yellowstone National Park to see amazing natural phenomena, like Old Faithful.

But who were the original Yellowstone visitors? Why did they go there? And what happened?

Archaeologists are digging up new clues and sifting the evidence to answer those questions.

Discover THE HIDDEN WORLDS OF YELLOWSTONE in this exclusive presentation based on the blockbuster Smithsonian magazine cover story.

You’ll hear directly from:

• Archaeologist Doug MacDonald, author of the book Before Yellowstone, who will discuss research findings that point to the presence of Native Americans thousands of years sooner than previously thought
• Scholar and activist Shane Doyle, a member of the Crow tribal community, who will share his unique vision of the park’s ancient history
• And photographer Andrew Geiger, who will give you a personal tour of the great Yellowstone wilderness, including never-before-published photographs

The presentation will be hosted by Smithsonian contributing writer Richard Grant, author of our cover story.

Join us for a one-time-only live event that reveals the secret history of Yellowstone on Thursday, March 18th at 7pm EST.
