About this map

Mark Twain Lake dominates this Ralls County landscape, its sprawling irregular fingers reaching into the surrounding timber and farmland. Created by the impoundment of the Salt River, the reservoir has fundamentally altered the geography of the region, drowning older crossings like Shaver Ford and Shepard Ford while creating new recreational hubs such as Indian Creek Marina and Blackjack Marina. Several small residential clusters and named points of interest hug the shoreline, including The Landing, Joanna, and Clear View.

Tracing the heritage of the area reveals historical sites that predate the reservoir, such as Utterback Cemetery and Crigler Cemetery. The landscape transitions from the open water and inlets to the uplands along Co Line Rd, where drainage from Little Indian Creek and Ely Creek feeds the basin. Modern infrastructure, including Highway A and numerous county roads like Co Rd-488, provides access to these waterfront communities and ridges like Flint Ridge and Cedar Ridge.
