Quarries in metamorphosed limestone worked from the 1700's to 1830. In 1820, there were five lime quarries operating in this area. It is said that the mortar made with Chelmsford lime was "so strong and clings so tenaciously, that bricks laid in it are not worth cleaning".

"Chelmsfordite" was described as a new mineral by J. F. Dana & S. L. Dana in 1818. This mineral was later determined to be scapolite. James Freeman Dana (1793-1827), was born in Amherst, New Hampshire, and was a chemist, professor and author. His brother, Samuel Luther Dana (1795-1868) was also a noted chemist.
