Believe it or not, no A.I. was used in the making of this flyer… 👀

You’ve heard the ghost stories. Now it’s your turn to investigate. 👻

Join Flagstaff Underground and Kelly Diffie inside Flagstaff’s historic American Legion Post #3 for a night of hands-on paranormal investigating.

Hold the meters. Ask the questions. Listen for a response. We’ll bring the tools and guide you through the investigation. You bring your curiosity… and a little courage.

Bring a friend you’d trust in a dark room. Only 20 spots available, and you don’t want to hear about this one afterward.

Reserve your spot at FlagstaffUnderground.com

Flagstaff has stories most people never hear.

Beneath the modern shops and busy sidewalks are the echoes of a rougher time. When saloons, railroad workers, gamblers, and pioneers helped shape the city we know today.
