2019 Map of Cosmos

About this map

The Salamonie River, Mississinewa River, and the headwaters of the Wabash River converge across this borderland of Indiana and Ohio. This area, spanning portions of Jay and Randolph Counties in Indiana and Mercer and Darke Counties in Ohio, is defined by an intricate network of drainage ditches such as Peden Ditch and Sheffer Ditch that support the region's agricultural productivity. The settlement of Salem sits near the western edge, while Cosmos serves as a landmark at the junction of Co Hwy 38 and Gray Br. Genealogists will find several burial sites preserved across the landscape, including the Pleasant Ridge Cem near Twin Willows Lake and the Hoover Cem along the Mississinewa River. The map illustrates the transition from the Stillwater River basin in the south to the northern river systems, connected by a rigid grid of rural routes like E Treaty Line Rd.
