Saint Marys and the village of Norwalk anchor this section of Monroe County, where the topography is defined by prominent landforms like Saint Marys Ridge and Summit Ridge. The landscape is a network of coulees and valleys, including Farmers Valley, Halls Valley, and Lyon Valley, each carved by small waterways such as Farmers Valley Cr and Brush Cr. A notable engineering landmark, the Number Three Tunnel, is situated near the northern ridge line, indicating the historical path of transportation through these steep elevation changes.
