Train cars and airplane parts in the Clark Fork River just west of Alberton were an unwelcome surprise for some Clark Fork floaters. Crews worked Friday near the Fish Creek exit, roughly 45 miles west of Missoula to clean up the mess after a train derailed Thursday.Officials announced Friday evening that a cleanup plan worked out between Montana Rail Link and Fish, Wildlife and Parks will allow them to open the river to floaters on Saturday. Three huge aircraft components are in the water, spilled from the derailment on the tracks above.
