Journeys in ancient and old growth forests
Charleston Lake 
The Hemlock Ridge Trail leads through rock crevices, and dense hemlock and white pine forest with views over wetlands. Most of the forest is under 120 years old.

The first hemlocks you'll come across on the hemlock ridge trail are dwarfed eastern hemlocks growing in the shade of red oak and other hardwoods. These small hemlocks are 5-10 m tall but commonly over 100 years old, likely about as old as many of the hardwood trees that tower above them. Soon you walk through a dense shady grove of hemlock - again most of the trees are 110-120 years old, though some older trees may have survived along the shoreline. It seems likely the area was logged around 120 years ago. This trail is worth visiting for the dense hemlock forest and for the fascinating geology, as you walk past striking sandstone ledges and through crevices.
