The Mianus River begins in Greenwich, Connecticut.  It flows north through North Castle, New York.  In Bedford it reverses its course and flows south through the gorge and then into Long Island Sound.


The river was named for Sachem Mayano of the Wappinger tribe, who was killed near the gorge in 1664, and whose name means "he who gathers together."

Formed in 1953, the Mianus River Gorge Conservation Committee fostered the pioneer land preservation project of the Conservancy.

1954 (Christmas Eve)  --  Gloria and Anthony Anable, two founders of the Mianus Gorge Conservation Group, learned that 60 acres of the gorge would be sold seven days later. The two Anables and a few others negotiated with the landowner and scrambled to procure a cash down payment. Some members pledged their life insurance policies; an intensive local fund-raising campaign amassed the rest.

1955 (New Year's Day)  --   a contract on the property was placed in the landowner's roadside mailbox before the 8 a.m. deadline.

1955 (July 1)  -- the scheduled deadline for the deal.  To beat the deadline, the group sought help from the newly formed The Nature Conservancy. The Mianus River Gorge is the "birthplace" of The Nature Conservancy's method of direct-action conservation. This was the first project the fledgling Conservancy became involved in when a group of local citizens came together to protect the gorge.

1964 --  the Mianus River Gorge was registered as a National Natural Historic Landmark.  It was the first natural area to be so designated.

There is a side trail shortly after Point B that leads to the Hobby Hill Quarry.  

Here mica, quartz, and feldspar were mined out of the Bedford augen gneiss in the 18th century.   At the quarry you can see the exposed white and pink quartz. Signs tell you not to collect any of the quartz.

The Bedford augen gneiss at Mianus River Gorge is generally assumed to be of Precambrian or early Paleozoic origin. Geologists estimate that the pegmatite, which intrudes into the gneiss, is around 375 million years old.


You can take one trail out that partly goes along the river, and then take another back that is set farther from the gorge itself.
