Milltown, Maine is a former town that is now part of the City of Calais, Maine and is located in the farthest reaches of Downeast Maine. In the spring the melting snow can cause the St. Croix River, which separates Maine from New Brunswick Canada, to rise dramatically. In 1923 the flooding caused by the melting snow was severe. What makes this interesting is that a Frisco boxcar was far from home when photographed in these two images.
This image shows the surrounding area. The left side of the river is Milltown, New Brunswick Canada (now St. Stephen, New Brunswick) and the right side is Milltown, Maine U.S.A.
Milltown is still the site of a U.S./Canada Border Crossing, and although rail traffic has largely dried up in the area, a small local still hauls logs from New Brunswick across the border to the Woodland Pulp Mill in Baileyville, Maine on the Woodland Spur of what used to be the Calais Branch of the Maine Central Railroad.
