Friends of Pine Hawk: Boxborough Esker Walk

The Boxborough Esker Walk in memory of George Krusen is sponsored by both the Boxborough Conservation Trust (BCTrust) and the Friends of Pinehawk.  The landscape of Boxborough was sculpted over millions of years, but some of the most dramatic features formed “only” about 15,000 years ago. The Beaver Brook Valley Preserve protects a beautiful example of an esker – a long, sinuous ridge of sediment that was formed under the edge of an enormous glacier at the end of the last ice age. Tufts geologist Anne Gardulski will guide the walk along the crest of the Boxborough Esker and explain how it formed, looking at the evidence in the sediments. Rita Grossman, BCTrust’s president, will also note how the efforts of George Krusen were key in protecting this significant geological feature from being fully excavated for gravel to build I-495.

George also deeply appreciated the Native American imprints on the land in our region. Brian McClain from Friends of Pine Hawk will point out possible Indigenous stone structures including those as described in the book Manitou, which will be discussed at the Pinehawk event taking place on November 13th.
