The Fort Wayne Moraine is considered contemporary to the last stages of the Valparaiso Moraine. Centered on Fort Wayne, Indiana, the northern leg of the moraine is mostly overlaid by the younger Wabash Moraine angling northeastward through Williams County, Ohio. It only becomes identifiable in Lenawee County, Michigan south and northeast of Adrian before ending in the intermingling of moraines around Ann Arbor. The south and eastern leg of the moraine follows the northern bank of the St. Marys River into the State of Ohio. At the north bend of the St. Marys River, the moraine arcs northeastward through Lima, continuing in a northward arc to reach north of U.S. 30 in Hancock County to pass through Upper Sandusky, again bending to the north to end 15 miles (24 km) to 20 miles (32 km) to the northeast.
