Revis Hill Prairie

Revis Hill Prairie is a protected area in Mason County covering about 412 acres with native grassland on elevated terrain and oak-hickory forest interspersed with ravines at lower elevations. The varied terrain reflects the legacy of glacial activity that shaped the landscape thousands of years ago.

The preserve was established in 1973 as a protected area, following the departure of glaciers that had left behind fine sediments and distinctive loess soils. This geological foundation enabled the development of the ecosystems visible today.

The preservation of Revis Hill Prairie represents Illinois's commitment to protecting natural grassland ecosystems through scientific management practices.

A windshield card is required when parking to document your visit. Certain activities are restricted to designated zones to protect the natural habitats.

The site harbors several uncommon plant species adapted to the specialized loess soil conditions found nowhere else in the region. Observing these plants offers a glimpse into ecosystems that exist in very few places.
