2021 Map of Kaskaskia

About this map

Kaskaskia Island dominates this stretch of the Mississippi River valley, where state and county lines shift through a complex network of sloughs and old riverbeds. The settlement of Kaskaskia and the nearby site of Old Kaskaskia sit at the center of this unique geography, bordered by the Kaskaskia River to the north. These communities are defined by a grid of local roads including La Grande Rue and N Kings Hwy, which connect the riverfront to the interior farmland. To the southwest, the town of St. Mary sits along Saint Marys Bend, where the terrain begins to rise away from the floodplains. Genealogists will find the Kaskaskia Cem and Saint Marys Cem clearly marked, while physical landmarks like Beaver Island and Idlewild Slough trace the persistent impact of the river's historical meanders on the Illinois and Missouri borderlands.
