This is no ordinary brother and sister duo; they are part of a legendary time travel family with a mission to preserve and protect our national parks and have developed a reputation for solving mysteries. As they time travel back hundreds, thousands, and millions of years, they not only learn about the past, but also experience it. They encounter all sorts of wild creatures and plants, meet the people involved in the establishment of the national park, learn about the Native Americans that call this land home, and unravel some of the park’s secrets.
