This obscure place apparently produced excellent crystals back in the 19th century (like so many other Haddam localities) and its precise location is uncertain. Davis (1901) is about the only one to document it:

Before closing this article I must allude to the magnificent specimens of black tourmaline obtainable here in crystals from the size of a needle to those four inches in diameter and twelve inches long. This variety is found widely distributed throughout the town. The most interesting locality is on the property of the late James C. Walkley, where it has been mined by the late Nathaniel Cook many years ago, and specimens sent all over the country. It occurs here in large veins of white passing into smoky quartz, lying between walls of gneiss. The finest and most brilliant crystals are found in the smoky quartz. The writer has seen specimens taken out of this mine as brilliant as polished pieces of jet, fresh from the lapidary's hand. I know of nothing, that for polish and perfection can approach these specimens, except those from Pierrepont, N. Y. These crystals are, as a rule, of considerable size, often weighing several pounds.

Pockets of feldspar are met within the quartz, which yield imperfect crystals of Orthoclase often penetrated by the tourmaline. At Yale and Harvard universities, and Academy of Natural Sciences, Philadelphia, may be seen specimens from this mine.

This place being on the property of writer's grandfather, a great lover of God's handiwork and an old pupil of the late Prof. Chas. U. Shepherd, that he received when a boy of ten his first lesson in mineralogy, and I can say that I have spent more time at that old mine than any other, and have the pleasantest reminiscences of it.


It may be the same place mentioned by Williams (circa 1945) simply as "Camp meeting woods, near Wells Brook, Black Tourmaline." Wells Brook is now known as Kriegers Brook, which flows under Walkley Hill Road where the 1859 map of Haddam shows the Walkley family had various properties. Williams' map shows the locality approximately 1000 feet SW of the intersection of the brook and the road. Residential development has taken over this area, the coordinates are very approximate.
