Westborough Community Land Trust invites the community on a Geology Trek Nov. 4, from 1:30 to 3 p.m., at Veterans” Freedom Park. Andy Koenigsberg will lead a walk from the park along the Malley Trail to the Pumphouse (round trip about 2.5 miles). Brief stops will highlight some distinctive geological features along the trail, such as the Marlborough rock formation, visible as outcrops in the park, as well as glacial features including moraines, eskers, and glacial erratics.
