1950 Map of Alma

About this map

The Upper Mississippi River Wildlife and Fish Refuge dominates the valley floor of this 1950 survey, where the Mississippi River creates a complex network of backwaters like Peterson Lake and Robinson Lake. The river's industrial character is marked by Lock and Dam No 4 near Alma, a primary settlement alongside the Chicago Burlington and Quincy railroad. To the west, the Zumbro River flows through Greenfield toward the village of Kellogg, while the Wisconsin bluffs to the east are carved by the Buffalo River and its many tributaries.
