Chimney Bluffs State Park

The Bluffs were formed by a glacial drumlin, or pile of ground up mud, sand, and stones pushed along by the glacier as it scoured the land. Over time, Lake Ontario grew and began eroding away at the northern end of the drumlin, exposing the cliffs. Wind, rain, and snow melt-water continue to eat away at the cliffs, reshaping the Bluffs and providing us with a dynamic landscape that can be vastly different from year to year.
