While visiting their grandparents’ farm in South Dakota, Max and Hannah discover hundreds of rocks piled up in the corner of a field. Puzzled, the twins ask Grandpa if he has the key to this mystery. How did all those round rocks get there?
In The Mystery of the Round Rocks, Grandpa describes the early, geologic history of South Dakota and the Great Plains. He takes the children on an amazing journey, riding along with the vast glaciers that carved out present-day flat farmland and the Missouri River, leaving behind thousands of telltale round rocks. Watch out for saber-tooth tigers and short-face bears, wooly mammoths, giant deer, and bison before Max and Hannah find the rocks and unlock their secret.
The Mystery of the Round Rocks is suitable for children with a second- to fourth-grade reading level or for reading to a younger audience.
