Ancient Secret of Central Park

☠️There's a boulder that hides an ancinet secret in Central Park.

Umpire Rock in the southwestern corner of the park has markings from the sudden melting of the last great ice age 13,000 years ago. At the time New York City was buried under 2,000 feet of ice!

No one really knows how the ice melted so fast, but it certainly has left its mark with the massive boulders that lie all around the city.
