🏆 10,000-Year Bog — One of New Hampshire’s finest quaking bogs — a 10,000-year-old floating peat mat with carnivorous plants
Heath Pond Bog Natural Area protects one of New Hampshire’s finest examples of a quaking bog — a floating mat of sphagnum moss that has been growing for 10,000 years since the last Ice Age. The bog’s surface literally bounces when you walk on it, as the floating peat mat undulates over the water below. Heath Pond Bog supports a remarkable array of bog plants including carnivorous sundew and pitcher plants, wild cranberry, Labrador tea, and rare orchids. The site provides a window into an ecosystem that once covered much of New England after the glaciers retreated.
