An old quarry in diabase, dating to before 1734, now almost entirely built over. The site was located within the boundaries of the town of Charlestown (now a part of Boston) until 1842, when the town (now city) of Somerville was established.

M. Edward Wadsworth wrote in 1878: The stone from this [locality]… has been used to a considerable extent in Boston, Cambridge, Medford, Maiden, Somerville, Brighton, and other towns, for basement walls, under pinning, steps, posts, fence walls, etc., and, when it is used above ground it compares very favorably with the other building stones used beside it, especially when hewn, a fact which is quite surprising when we consider its ready disintegration in the parent bed. The oldest monument of its use in Cambridge… is the old mile stone, now standing near Dane Hall, which bears date of 1734. The front of the building now occupied by the Cambridge Gas Light Company at Harvard Square is of this rock, and was erected in 1840.
