For students ages 10–17. A Discover series program combining earth science, geology, archaeology and history. Students explore the secrets of a 200-year-old homestead and how its environment influenced early settlers. Offered in partnership with Little Antietam Creek, Inc. (LACI). Students join Buttonwood educators and LACI archaeologists to “dig into the past” at historic Stoner Farm—digging and working with artifacts, scientific testing of the properties of limestone and soil, using remote sensing, learning how limestone is cut, and mortar is made, and more. Camp fee: $50 for members of Buttonwood Nature Center; $55 general public. Space is limited; register online at buttonwoodnaturecenter.org.
