The National Park Service is trying to find the culprits behind a Wyoming ghost town cemetery vandalism spree that damaged several historic tombstones.

Kane, Wyo., about two miles from where Shoshone and Bighorn rivers meet in Big Horn County, was abandoned around 1965 when the Yellowtail Dam in Montana flooded the area surrounding the small town.

The cemetery, located on higher ground a few miles north of where the town stood, wasn't inundated.

Park officials from the Bighorn Canyon National Recreation Area, which straddles the Wyoming-Montana border, first noticed the vandalism on Nov. 4, then saw additional vandalism the evening of Nov. 13, KULR-TV reported.

They said several headstones have been knocked down or broken and others have been painted with spray paint.

Inhabitants of the cemetery include Mormon settlers who came to the region a century ago.
