"There is an old garnet mine located on the side of the hill just north of an old road running east from Middle Haddam.", Schairer (1931).
Schooner (1958) mentions it briefly in a few places:
"A brown mineral, closely resembling anthophyllite, is abundant in gneiss at the old garnet mine in Middle Haddam...
"Large reddish [staurolite] crystals, unfortunately rough and of very poor quality, can be found in the ledges near the old garnet mine in Middle Haddam....
"Last worked in 19th Century (?)."
A resident and collector has described it as beside the road and not much more than a small prospect pit about 3 meters square, the garnets of poor quality and generally hidden in the matrix.
Coordinates are approximate. Area is residential private property.
