Ellison Bluff features a densely wooded two-tiered rock terrace -- part of the larger Niagara Escarpment rock formation that stretches and winds though the site providing spectacular views from the bluff tops. Extending from New York, into Wisconsin and forming the Door Peninsula, the limestone-capped Niagara Escarpment was formed through sediment deposition of inland seas more than 425 million years ago and contains fossil-rich sedimentary bedrock. Over time, the soft rocks under a more resistant limestone cap wear away leaving bluffs, which rise 200 feet above the Bay's shore.
Ellison Bluff is owned by Door County and was designated a State Natural Area in 2002.
