Archaeologists studying a prehistoric site in Golden, Colorado, have found that people lived there thousands of years earlier than previously thought.

The site is called “Magic Mountain” after an amusement park that used to own the land back when excavations started in the 1950s.

Archaeologists like Mark Mitchell knew that people, likely nomadic hunter-gatherers, had lived and camped at the site for much of the last 5,000 years.
