Devils Tower, WY (AP) Just like in the science-fiction movie “Close Encounters of the Third Kind,’’ UFO enthusiasts are being drawn to a strange geological formation in Wyoming.

Devils Tower played a key role in the well-known UFO film that came out 40 years ago this year. The first Devils Tower UFO Rendezvous will be held at the site from Sept. 14-16.

The formation is actually the solidified core of an ancient volcano. Experts on UFOs will speak at the convention.

Organizer Brian Olson tells KOTA-TV that there’s a fun side, too, with plans for a parade, live music and barbecue cook-off.

Devils Tower stands more than 800 feet (243 meters) tall and can be seen for miles.
