GREEN LAKE Author Chad Lewis will speak about some of Wisconsin's most spooky locations during a presentation at 6:30 p.m. Thursday at Caestecker Public Library, 518 Hill St.

Green Lake's own Dartford Cemetery is one of those places. Local legend has it that the cemetery is haunted by Chief Highknocker and a host of young children's ghosts. Some people claim they have been flung off a certain mausoleum by unknown spirits.

Activities in Dartford Cemetery were the subject of an episode of The Discovery Channel's series, A Haunting, last year. The program sparked national headlines about the cemetery and its legend, according to Lewis.

He is the co-author of "Wisconsin Road Guide to Haunted Locations."

The presentation by Lewis will be held in the meeting room and is expected to take about an hour. There is no charge. The Friends of the Library are sponsoring the event.
