About this map

The Iowa River carves a deep valley through the center of this landscape, its winding course defining the transition between Hardin and Marshall counties. In the mid-1970s, the agricultural character of the region remained firmly anchored by the settlements of Union and Liscomb, both connected by the Chicago and North Western railroad. The map provides a detailed view of rural life, specifically through its numerous family-named burial grounds including Miller Cem, Bunch Cem, and Everist Cem, which serve as vital markers for genealogical research. Conservation efforts are evident in the sprawling Grammer Grove County Wildlife Area and the County Forest Reserve along the river bluffs. To the south, Mormon Ridge and Mormon Lake recall historical migration patterns, while the presence of several Gravel Pits indicates the local extractive industry that supported the area's road networks.
