Newark Earthworks

🍄🎃 A little autumn color has popped up at the Great Circle! 🎃🍄

These beautiful orange mushrooms are eastern jack-o’-lantern mushrooms, a species commonly found throughout Ohio. You can spot them growing in clusters near hardwood trees, old stumps, or even buried roots. They have an unusual natural trick of their own—the gills can produce a faint greenish glow in darkness! As beautiful as they are, these mushrooms are poisonous and should never be eaten.

🍂 Have you spotted any jack-o’-lantern mushrooms this fall?

We loved having the fourth graders from John Clem Elementary visit the Newark Earthworks! ❤️🤍

It’s always exciting to see students explore the Octagon and Great Circle and connect what they’re learning in the classroom to the incredible history and culture right here in their own community.

Thank you to John Clem Elementary for bringing your students out to explore our World Heritage Site! We hope to see you again! 🌎
