Niagara Escarpment Field Day
ALL PROCEEDS FROM OUR EVENTS, WORKSHOPS, & CRUISES SUPPORT OUR HISTORIC PRESERVATION MISSION.
YOU can help play a part in saving the historic maritime structures on Plum and Pilot Islands!
Everything you ever wanted to know about the Niagara Escarpment - but were too afraid to ask
The incredible cliffs on the western side of the Door Peninsula are a part of the same Niagara Escarpment which the powerful Niagara River slices through at Niagara Falls. This rock ridge extends more than 650 miles through Central and Northeast Wisconsin, the upper peninsula of Michigan, Southern Ontario, and upstate New York. (See map)
​​
Join Don Mikulic, with the Niagara Escarpment Resource Network (NERN) to learn about the globally significant unique features of the escarpment; natural, cultural, historical and environmental.
After the presentation, take a hike to see where the escarpment is present on Plum Island and learn about the plants that are dependent on this rare geologic formation.
Transportation from Gills Rock provided aboard FOPPI’s charter boat, The Shoreline.
