We're continuing our week-long series, This Land: Rediscovering Colorado's National Park with a trip to the mysterious Mesa Verde.

9NEWS Reporter Kyle Clark and Photojournalist Chris Hansen take you to the seldom-seen side of the National Park to learn about the people who lived there and the lessons they left behind when they abandoned the now-famous cliff dwellings.

Watch the video above to see what they found.

And be sure to join us on Saturday night on 9NEWS for an hour-long special that airs at 9 p.m. The special re-airs on Sunday at 9:30 p.m. on Channel 20.
