Chimney Bluffs State Park Trails Professional Guide
Detailed Trail Description from our Guidebook
"Chimney Bluffs is a glacial drumlin cut to sharp spires, 150-feet-high, by wind and wave action. Drumlins are long, narrow, rounded hills of sediment (sand, clay, silt, gravel, cobbles and boulders), formed when the glaciers scoured the countryside. The last glacier to cover this area, melted 12,000 years ago. The drumlin at Chimney Bluffs has a high clay content that acts as a cement, binding gravel and cobblestones together. Still, the cliff face continues to erode, as much as 5 feet per year in places, making the cliff edge trail dramatic but dangerous. The drumlin field of which Chimney Bluffs is a part, is one of the most extensive in the world, with over 10,000 drumlins. These ridges sit northsouth across this region and resemble an old-fashioned washboard. Surface: Mowed grass and dirt trails. One short paved trail."
