Brown (1930) documented some scattered mineral finds in Stamford:

"In Stamford, at the West Avenue Quarry located about one and one-quarter miles from the center, fine specimens of blue microcline feldspar, radiations of stilbite, augite, and a few crystals of pyroxene have been found.

"At Shippan Point a number of years ago a drift boulder of vesuvianite was found.

"On North Stamford Avenue about two miles from the center, good sized iron garnets have been obtained."
