1962 Map of Blanchardville

About this map

Blanchardville sits at a critical junction of the Pecatonica River and the Illinois Central Railroad, serving as a central hub for this portion of the Driftless Area during the early 1960s. The landscape is defined by its dendritic drainage patterns, with numerous valleys like Star Valley and Jeglum Valley carved between high ridges. A significant man-made addition to the natural terrain is Yellowstone Lake, surrounded by the Yellowstone Conservation Area, which transformed the local hydrology of the Yellowstone River.
