1. Milwaukee Railroad Marker
The Milwaukee ran through a region of river and creek valleys making for the building of many bridges. The Yellowstone was crossed three times between Terry and Miles City. The first is five miles west of Terry, the second 25 miles further at Tusler Creek, and the third 5 miles West of Miles City.
Supplies to build the Milwaukee Railroad first came by rail on the Northern Pacific tracks, then across the Yellowstone River by boat, ferry and cable.
The Old Milwaukee Railroad Bridge is about 3 miles West on Milwaukee Road.
Calypso was a stop on the Milwaukee Railroad. The community had a school and a ferry crossing in addition to the railroad section houses.
An interpretive sign reached by crossing the Old Milwaukee Railroad bridge marks the beginning of the Calypso Trail. The rustic 5 1/2 miles trail leads to the scenic Terry Badlands.
