Almon Underwood Prairie Forest Preserve
Underwood Prairie is a dedicated Illinois Nature Preserve covered with high quality, aboriginal, dry hill prairie plants. There are more than 50 prairie forbs and shrubs creating an exquisite display of color throughout the blooming season.
Located on South Lorang Road, approximately 3/4 mile south of Main Street, 1/2 mile north of Seavey Road in Kaneville Township.
The structure of Underwood Prairie is a series of small undulating gravel knolls that are part of the Kaneville Esker, Illinois' longest esker that was deposited here between 10,000 and 20,000 years ago. It is believed that eskers were formed by glacial debris washing across the massive ice sheets into sinuous cracks or chasms in the ice which later melted leaving this wandering, linear imprint on the landscape.
