Located in the City of Mequon, Fairy Chasm State Natural Area is 19 acres. This preserve contains an 80 to 100-foot deep chasm created by the flow of Fish Creek, a small stream that drains into Lake Michigan. Due to the cool lake winds and a north-facing geography, it also contains a unique microclimate that mimics more northern habitats. This colder habitat allows species such as sphagnum moss, beaked hazelnut and dwarf scouring rush – not often found this far south – to survive and thrive. The northern slopes of the chasm feature forests of white pine, yellow and paper birch and white cedar; while its southern slopes are the habitat of juniper and trees found in mesic forests such as beech and sugar maple.
Access is limited due to parking restrictions.
