My first stop today was at the Saw Mill Brook Conservation Land. It’s not very big (27 acres/11 hectares), but it is a gorgeous place. Saw Mill Brook makes its way through the ruins of two dams (a saw mill dam on the Burlington/Wilmington bounds and an upper dam well within Burlington that presumably held battery water storage for the saw mill a hundred yards downstream). The main lower dam is a granite block dam dating from the early eighteenth century and may have been designed by Loammi Baldwin, native of nearby Woburn and America’s first civil engineer. The brook runs through an actual canyon as it makes its way into Wilmington which is relative unique for this area. #sawmillbrook #burlingtonma #wilmingtonma #conservationland (at Burlington, Massachusetts) https://www.instagram.com/p/B-sv_KcBcyW/?igshid=1pnbm19fq9lkm
