CASPER, WYO. --- Three men who pleaded guilty to taking part in rolling large boulders into the Pathfinder Reservoir Dam last June have been ordered to pay fines, perform community service and serve probation.

The Casper Star-Tribune reports 25 -year-olds Lawrence Earl Rowland Jr. and Lyle James Hartman and 24-year-old Geran E. Minton received their sentences in federal court earlier this month.

All three were sentenced to six months probation. In addition, Hartman and Minton were fined $2,000 each and ordered to perform 48 hours of community service, while Rowland was fined $1,000 and ordered to complete 32 hours of community service.

The three faced charges after a youtube video surfaced June 14 with the caption, "
