SOUTHEAST, NY — An archaeologist has found ancient tool fragments and other artifacts at the site of a suburban New York sewer construction project.

The find was made around Peach Lake, in the Putnam County town of Southeast.

Archaeologist Michael Pappalardo says the artifacts also include pottery shards; a 2 1/2-inch blade; tips for arrows or darts; and stone flakes that show tools were made there.

It's believed the artifacts are about 1,000 years old. They're being donated to the Southeast Museum in Brewster. The dig was required by state and federal historic preservation acts.

The sewer system is being built to protect the water quality of the lake and the New York City reservoirs to which it's connected.
