Fort Wayne Moraine

Fort Wayne Moraine is a glacial formation that extends along the northern bank of the St. Marys River with an undulating surface pattern. This ridge was created by rock and sediment deposits during ice age periods and shapes the land across multiple counties.

This formation developed during the final stages of glacial activity in the late Pleistocene period. The moraine emerged as part of a larger ice age system that reshaped the region's landscape.

The old Piqua Road in Allen County, Indiana follows the natural crest of this formation, marking a traditional transportation route that has guided travelers for centuries.

The area offers opportunities to observe the natural watershed between two river systems from the elevated ridge. The main crest rises noticeably above surrounding riverbeds, providing good views of the landform itself.

Near Lima, Ohio, three parallel moraines run alongside the main crest and form a series of distinct geological ridges. This multiple ridge pattern reveals the complex processes that occurred during glacial retreat and readvance.
