THOMASTON — The Thomaston Grammar School’s rock garden has become a reality, securing their first “crop.” Together with Thomaston Public Works employees and their teacher, Thomaston Grammar School fifth graders have designed and implemented the newest outdoor learning space at the school.

Lynn Snow’s fourth- and fifth-grade science students spent many weeks this fall studying geology. To culminate the unit, the group decided to create a space to showcase some of Maine’s sedimentary, metamorphic and igneous rocks. On Tuesday, Dec. 13, despite the frigid temperature, the first specimens were placed in the designated area. These inaugural rock donations include a throne-like piece of granite from George C. Hall & Sons, two beautiful pieces of marble from Dragon Cement and long pieces of granite given by the Thomaston Federated Church. The ballast rock that covers the area was repurposed from the old Lura Libby School roof. Other pieces will be added in the future including an engraved rock sign. Snow and her students are still seeking large rock and mineral donations to add diversity to their new “garden.” Contact Snow at for more information.

The TGS Rock Garden is open for the public to visit outside of the school’s hours. Rock and mineral identification signage will be placed in the spring. The area is located between the school’s Common Ground Garden and fruit orchard.
