2021 Map of Savanna

About this map

Savanna and Sabula face each other across a complex network of islands and backwaters on the Mississippi River in this 2021 study. The landscape is defined by the massive river channel and the intricate hydrology of the Savanna Islands, Dixie Islands, and Eldridge Island. Inland from the river bluffs, the terrain transitions to the agricultural uplands of Samoa and Teeds Grove. The map records several small family and parish burial grounds that reflect the area's long-standing settlement patterns, including Canada Hollow Cem, Dickinson Cem, and Simpson Cem. Transportation infrastructure is anchored by the Savanna Sabula Bridge, connecting the Illinois and Iowa shorelines near the Savanna Township Cem. Numerous lakes and sloughs, such as Town Lake and Little Keller Lake, highlight the active floodplain environment.
