Mastodon State Historic Site preserves one of Illinois' most significant Ice Age fossil discoveries, offering visitors a unique glimpse into prehistoric life alongside family-friendly outdoor exploration.
Mastodon State Historic Site, located near Morris, Illinois, is a remarkable archaeological and paleontological preserve established to protect the remains of a mastodon discovered in the early 20th century. The site spans a section of open prairie and woodland along the Illinois River valley, providing habitat for local flora and fauna while serving as a window to the region's Ice Age past. The discovery of the mastodon fossils, along with other prehistoric animal remains and Native American artifacts, highlights the area's importance both scientifically and culturally. Visitors can explore a variety of gentle walking trails that wind through prairie grasses and wooded areas, with informational signage telling the story of the mastodon excavation and early human history.

Outdoor activities include hiking, birdwatching, picnicking, and seasonal events geared toward families and school groups. The landscape offers a quiet natural setting where visitors can experience Illinois' prairie ecosystem and learn about the interaction between Ice Age megafauna and early humans.
