National Parks Facts

Jhonatan Gonzalez was hiking the Narrows at Zion National Park with his family - kids as young as 1 - when the calm river suddenly turned waist-deep and raging, choked with logs and debris. He and his brothers planted themselves in the current and formed a human chain. Strangers on the bank grabbed on. Dozens of hikers, including toddlers, passed hand-to-hand to safety. Everyone made it out.

Mount Rushmore has a secret: a 70-foot granite tunnel cut directly behind the faces. Sculptor Gutzon Borglum began drilling it in 1938 to house America's founding documents for future civilizations. Congress shut the project down in 1939 and Borglum died in 1941. In 1998, his family lowered 16 porcelain panels into a titanium vault and sealed it under a 1,200-pound granite capstone. Nobody can go inside.

Death Valley is the hottest, driest place in North America. In February 2024, record rain turned its lowest point into a temporary lake called Lake Manly. It stretched six miles long and three miles wide, but only a foot deep. Death Valley has no outlet to the sea, so a lake this size almost never forms. People still grabbed kayaks and paddled across it.
