Natural Features

The distinctive profile of Lyme’s 3,238-foot Smarts Mountain, in the northeastern corner of the town, stands tall on the Upper Valley horizon. Smarts, Holts and Winslow Ledges, and smaller hills rolling through the eastern and central parts of town are home to a healthy variety of wildlife, from black bear, fisher, and moose to the once-endangered peregrine falcon.
Hewes, Grant, and Trout Brooks flow from these heights to the flood plain of the Connecticut River at the town’s western border. Quiet Trout and Pout Ponds punctuate these streams, while Post Pond, in the lower valley of Trout Brook, echoes with the voices of children at the town beach. The river terraces along the Connecticut harbor some of the richest agricultural soils in New England.
