Three subjects were skiing the Catamount Trail starting at Bolton Valley and ending at Nebraska Valley Road. When they reached the downhill section they found conditions too difficult to continue and were overcome by darkness. They had no lights and called for assistance. Location was determined to be a short distance below the junction with the JK Trail. A hasty team from Stowe Mountain Rescue was sent up the Catamouth Trail from Nebraska Valley Road and assisted the subjects back to their car.
