As with many of our other protected lands (Lover’s Leap State Park, Burr Pond State Park, the White Memorial Foundation), the Hidden Valley Preserve of Washington’s Steep Rock Association was once the site of industrial operations. The Hidden Valley, quiet today except for the sound of the rushing Shepaug River, once echoed with the sounds of quartz mining and locomotives. The glories of a New England Fall presents the perfect time to visit this piece of Litchfield County’s industrial heritage.
Quartz, the most common mineral on the earth’s surface, was an important industrial product in American history. Initially quartz was used for knives, scrapers, and arrowheads. With the coming of the industrial revolution, the uses of quartz changed. It was pulverized and used as a filler in paints. (The Bridgeport Wood Finishing Company, a major paint-making operation, was located just a few miles away along the Housatonic in New Milford.) Another use of quartz was as an abrasive, like sandpaper. The primary use of quartz, however, was for glass, which is essentially melted quartz.
The hiker needs no excuse to travel to the beautiful woods of the Hidden Valley, but keeping one’s eyes open reveals a rich part of the county’s history.
