1. Thursday, October 15, 7PM – a talk at the Acton Memorial Library

Stone Prayers: An Update to the Inventory. For more than a decade, Prof. Curtiss Hoffman has investigated the thousands of enigmatic stone monuments scattered throughout the woodlands and fields of the eastern United States and Canada. Regional descendant Indigenous communities identify these structures as "stone prayers"—sacred sites that deserve protection from encroachment and desecration. Hoffman will share the latest findings from his continuing research which extends his landmark 2018 book Stone Prayers. His research, conducted at the request of the Narragansett Tribal Medicine Woman and with the approval of the United South and Eastern Tribes, Inc., documents compelling archaeological and environmental evidence supporting the Indigenous origin of many of these monuments

3. Tuesday, October 27, 7 PM, a talk at the Acton Memorial Library

The Big World of New England's Native Americans. From the Paleoindian period, beginning almost 13,000 years ago, to today, New England’s Native Americans have participated in many social networks throughout the continent. Robert Goodby, an archaeologist and Professor of Anthropology at Franklin Pierce University, will focus on the evidence for long-distance connections among Native communities over time, looking at evidence for sharing of technological traditions, religious practices, raw materials, and economic strategies, some of which spanned the continent or extended all the way down the Atlantic Seaboard from Maine to Georgia.

4. Thursday, November 5, 7 PM a talk at the Acton Memorial Library

Ceremonial Landscapes and the Algonquian Calendar. Ceremonial Landscapes mark key events such as annual fish-runs, planting and harvesting corn, storytelling, and maple syrup gathering. The night time sky's celestial patterns are encoded in stone features. Cathy Taylor, a former member of the Upton Historical Commission's endeavor to save the Upton Stone Chamber, will talk about these features. As an Upton resident she has explored and observed local ceremonial landscapes and calendar events closely over the years. She is a former board member of the New England Antiquities Research Association (NEARA) who writes articles, leads walks, and has worked to map and preserve sites identified by Tribal Historic Preservation Officers

6.   Tuesday, November 10 at 7PM, a talk at the Acton Memorial Library

The Algonquin Atlantic. Over the past two decades, documentary film producer Ted Timreck has presented to Friends of Pine Hawk audiences more than any other speaker.  Rather than show a finished film, Ted will present the early phase of a still-developing research project. In the tradition of his "Hidden Landscapes" video series, this project will highlight new developments in the discovery of Native American Ceremonial Landscapes in the Northeast. Rather than offering definitive conclusions, he will present multiple lines of evidence that suggest promising directions for further investigation.

A Peabody Award winning director, Ted Timreck has been associated with the Smithsonian's National Museum of Natural History for over 45 years.

7. Sunday, November 15, 1-3 PM, a community event at NARA Park

Fish Weir Creation Event.  Curious about how fish was harvested thousands of years ago using natural materials and the flow of brooks and tides? Come to NARA Park in North Acton with the whole family and participate in building a fish weir, a fence-like structure of intertwined wood and brush used by early Native American people to catch fish.

The activity will be led by Ian Bergemann, Acton’s Open Space & Trails Manager, with guidance from Strong Bear Medicine of the local Nashoba tribe and Littleton historian Dan Boudillion. Details will be emailed to registrants a few days in advance. Limited to 35, all ages welcome with adult supervision.

8.  Saturday, November 21, 10-11AM,  a talk at the Sargent Memorial Library.

Boxborough’s Beaver Brook Valley Preserve (Esker) Presentations. The presentations at this event will describe some of Boxborough's pre-history and will also provide helpful context for those who also sign up for the George Krusen Memorial Boxborough Esker walk at 1PM later that day (see event 9 below). Geologist Britt Argow will discuss not only how the local landscape developed over millions of years but also how Boxborough's esker was sculpted much more recently in the last Ice Age.  Local historian and author Brent Ranalli will provide an overview of the local Native American cultural history - especially the critical contact period when Europeans arrived three centuries ago.   Rita Grossman,  the Boxborough Conservation Trust's president, will note how George Krusen's efforts were key to protecting this significant geological feature from being fully excavated for gravel to build I-495.
