A group of quarries in gneiss located within Baltimore City near the junction of Stony Run and Jones Falls. The Harris Quarry is the most famous and is the type locality for haydenite and beaumontite. Provided many classic specimens cited in older mineralogy texts. Minerals listed are from the host gneiss, pockets within the gneiss and pegmatite dikes cross-cutting the gneiss.
