Big Rock: The Power of Glaciers
On the East Side, Big Rock is a 25-minute hike from Big Rock Visitor Station if you take the shorter Woodland Trail (.6 miles), and a 40-minute hike if you take the longer Heritage Trail (1.3 miles). Both trails lead you through oak and maple woodland habitat. Interpretive panels along the short paved loop at the Visitor Station help you explore the geology and native plants you will discover as you walk the longer Heritage Trail.
Big Rock itself is a huge granite boulder left by glaciers 14,000 years ago. Interpretive panels at Big Rock tell the story of an abandoned saw mill road used by pioneer settlers to harvest the important oak trees growing there.
