A hilltop meadow offering views of historic Lancaster.

As the last glacier moved across and scoured the New England landscape, the migration formed glacial drumlins, hills running parallel to the direction of the glacial flow, like Dexter Drumlin.

Today the reservation is a graceful, open meadow managed for ground-nesting birds (though hay is cut from the meadow after the young birds have fledged from their nests). A small tributary of the Nashua River runs along the western side of the hill, and a narrow, one-mile mowed footpath leads over the top and around the drumlin, the perfect way to experience its scenic views. When the flakes start to fall, the hills become a favorite local spot for winter sledding.
