Fourth Connecticut Lake: Peatland System
Description: This unusual northern tarn is at the uppermost headwaters of the Connecticut River, and has a floating bog and numerous insectivorous plants. The exemplary peatland here is a medium level fen system, and can be observed up close where the trail approaches its edge. Look out on the peat mat for buckbean plants (Menyanthes trifoliata), a distinctive member of the Gentian family with three oval basal leaves. The circular perimeter trail crosses several small streams that flow into this wetland, and two outlet streams that drain it at its southern end. The Connecticut River is so small at this point that you can step across it with ease.
Directions: From Pittsburg, take Rte. 3 north for 22 miles to the US/Canada border. Park at the border patrol station (sign in at the customs station), follow the trail west along the Canadian border for 3,000 feet to a trail leading south (preserve entrance), and follow for 800 feet to the pond and perimeter trail.
