Siegenthaler-Kaestner Esker State Nature Preserve

The preserve spans 37 acres of protected land featuring an ancient esker formation, which forms a natural ridge across the landscape with sand and gravel deposits.

The natural features within the preserve were formed during the Wisconsinan glaciation period between 11,000 and 25,000 years ago through ice-walled stream channels.

The land serves as an educational site where students and researchers study the geological processes that shaped the Ohio landscape during the last ice age.

Visitors can access the preserve through designated trails that lead to observation points of the esker formation while following conservation guidelines established by the management.

The preserve contains three distinct glacial formations in one location: an esker, a kame, and a kettle, making it valuable for geological research.
