For nearly 100 years, the Stoneyhurst Quarry in Potomac, Md., provided mined gneiss and mica schist (similar to granite) for homes, bridges and other projects. Then, it sat dormant for two decades.
It is now the site of a luxury condo complex. Homes at the 97-unit Quarry Spring development can sell for between $1.3 and $4 million, and residents love the rocks, waterfalls, and scenery. Homes built in quarries are also more resilient towards earthquakes, landslides, and heavy rainstorms.
Other quarry projects include the Jade at Monte Vista in the San Francisco Bay Area, and similar developments in Vancouver, Toronto, and Barcelona.
