Leo Petroglyph is an outstanding example of prehistoric Indian inscriptions.

On the edge of a beautiful ravine, the sandstone petroglyph contains 37 incised drawings of humans, animals, and human and animal footprints. It is now protected by a roof and viewing platform. The carvings, whose meaning is unknown, are attributed to Fort Ancient Indians who occupied this area between AD 1000 and 1650.

A trail leads through the gorge and along the unglaciated Mississippian sandstone cliffs that are 20 to 65 feet high. Wildflowers and birds are abundant during the warmer months.

The Leo Petroglyphs State Memorial is a historic site located in deforest, Ohio. It is home to a collection of unique ancient rock carvings, known as petroglyphs, that were created by prehistoric Native American cultures.

The petroglyphs at Leo Petroglyphs State Memorial were likely made by the Hopewell culture, which thrived in the region from approximately 200 BC to 500 AD. The carvings are believed to be several thousand years old and depict various forms, including animals, humans, geometric shapes, and abstract patterns.

The site was discovered in the 1800s by pioneers settling in what is now Warren County, Ohio. The carvings were found on a large sandstone boulder near the Little Miami River. The significance of the petroglyphs was recognized, and the site was designated as a state memorial in 1964.

The petroglyphs have been a subject of fascination and study for archaeologists and historians. They provide valuable insight into the cultural and artistic practices of the indigenous people who occupied the region in ancient times. However, due to their delicate nature, access to the petroglyphs is restricted to protect them from vandalism and deterioration.

Visitors to Leo Petroglyphs State Memorial can explore a small interpretive center, which offers information about the history, cultural context, and preservation efforts surrounding the petroglyphs. The site provides a unique opportunity to witness and appreciate the artistic achievements of Ohio's ancient inhabitants.
