Sappington, Montana is located railroad "west" of Three Forks on the eastern side of the Rocky Mountains. Here the Milwaukee Road crossed the Northern Pacific at grade and traversed the south side of the Jefferson River while the NP ran on the north side through Jefferson Canyon. Long ago a tower guarded the crossing, but was removed sometime prior to Ron V. Nixon's photo of an eastbound Milwaukee Road train on September 15, 1979. Today, the Montana Rail Link runs the old Northern Pacific line and only rolling mounds of prairie grass mark where the Milwaukee crossed.
