Upland Trail

2.1 miles, 97 feet of elevation gain, 2% average grade, 4% maximum grade
Hike time: 1.5 hours

The Pinhook Bog Trail System features two very different habitats. The Upland Trail highlights a rich beech and maple forest growing on top of a glacial moraine formed about 15,000 years ago. The Bog Trail leads to a bog in a depression in the moraine created when a large piece of ice broke off the melting glacier. The bog features an incredible habitat with unique plants.

This featured hike is a lollipop shaped trail. Starting at the parking lot trailhead, take the trail east to the junction with the loop trail. The preferred direction is clockwise or to the left. The trail winds through mature beech and maple forest as you hike over the undulating moraine topology. There is a nice view of the bog near the south end of the loop. Upon returning to the loop junction, turn left and follow the trail back to the parking lot.

History and Background
Bogs like Pinhook are relics of our glacial past. Trapped in the pulverized clay and rock left behind by a melting glacier, the bog began as a kettle lake. Cut off from ground water, Pinhook's water gradually became acidic. Sphagnum moss, tolerant of acidic waters, formed floating mats that eventually supported carnivorous plants like pitcher plants and sundew, orchids like pink lady's slipper and ferns. Over time, blueberry and holly shrubs colonized this unique acidic bog, eventually giving way to larger trees like tamarack and red maple. Pinhook Bog is on the National Natural Landmark list.
