Beginning in 2017, and with assistance from volunteers and the Thomaston Historical Society, archaeologist Harbour Mitchell undertook archaeological testing in an effort to locate any remains relating to Thomaston’s early-18th-century fort or General Henry Knox’s late-18th-century home. The testing effort was conducted over a period of two years in a large field between Thatcher Street and the railroad tracks in Thomaston, behind the Lyman-Morse Boatyard and behind where Fort St. Georges and Montpelier had been. Much of what Mitchell found wasn’t what he expected — household bits from the Knox era. On Tuesday, September 11, at Watts Hall in Thomaston, Mitchell will discuss the initial 2017 archaeological effort, its results and conclusions, and review the initial findings from 2018’s expanded archaeological excavations. There will be refreshments and socializing at 7 p.m., with the presentation starting at 7:30 p.m. The program is presented by the Thomaston Historical Society and the General Henry Knox Museum.
