USGS Topo · Published 1950About this map
Portal stands as a vital rail hub on the international boundary between the United States and Canada, where the Soo Line and Minneapolis St Paul and Sault Ste Marie railroads intersect. This 1950 survey documents a landscape defined by the prairie’s natural drainage and its emerging industrial footprint, particularly the strip mines and pit mines clustered near Lignite. The presence of the Swedish Cem and Norwegian Cem alongside Tonset Ch speaks to the specific immigrant heritage of Burke County during the mid-century era.
