The Rockland Public Library will present a slide-presentation by Arthur Spiess on the pre-European archaeology of the St. George River on Thursday, April 8 at 6:30 p.m. in the Friends Community Room. Spiess is the senior archaeologist of the Maine Historic Preservation Commission.

The St. George River drainage is rich in archaeological sites that span the entire length of human history in Maine. Spiess’ slide-talk will focus on the early inhabitants along the river. Native Americans have called the St. George River drainage home for nearly 13,000 years. In that time many cultures have come and gone, leaving behind bits of pottery, chips of stone, broken spear points, exquisitely crafted artifacts, and not-so-elegant food remains. Archaeologists, with the help of many volunteers, have been finding and excavating these sites with the goal of studying societies that no longer exist and that did not leave behind written records. The slide-talk presents an overview of St. George watershed prehistory and some of the important archaeological work that has taken place in the region.

The free event is co-sponsored by Georges River Land Trust as part of its annual Walks & Talks series that connects people with the vast outdoor resources of the Georges River watershed and surrounding areas. For more information call the library at 594-0310.
