1950 Map of Alma

USGS Topo · Published 1973

About this map

Mississippi River navigation and transport dominate this mid-century look at the border between Wisconsin and Minnesota. The river's complex network of sloughs and lakes, including Peterson Lake, Robinson Lake, and the Pomme de Terre Slough, is anchored by the presence of Lock and Dam No 4 near Alma. The terrain shifts abruptly from the wide river valley to a high, dissected landscape of ridges like Alma Ridge and Huber Ridge, separated by deep coulees and valleys such as Norwegian Valley and Dry Coulee.
