Tannersville Cranberry Bog

Tannersville Cranberry Bog was one of The Nature Conservancy’s first preserves. The relict boreal bog was once a huge glacial lake. Since the ice receded 10,000-15,000 years ago, approximately 40 feet of peat has accumulated on the floor of what was once a 715-acre lake. Today, the bog stands out in contrast to the surrounding forests. **Guided Tours Only**
