It lies 15.7 miles north-west of Delta Township, MI (from Delta Township, MI: bearing 309°T), and is situated 6.7 miles south-west of Westphalia. The soil here, a rich loam, supports rows of corn and soybeans that stretch to the horizon, punctuated by stands of oak and maple trees that blaze with color in the autumn. Beyond the town's edge, the landscape unfurls like an old quilt, pieced together with pastureland and the occasional weathered barn, its red paint faded by decades of sun and wind. The air often carries the scent of damp earth and ripening grain, a perfume of the agricultural heartland that defines this place. The history of Portland is deeply entwined with these rivers, which once powered mills and served as vital arteries for commerce. Early settlers, drawn by the fertile land and the promise of industry, established a community that grew around the confluence, its economy built on agriculture and the processing of its bounty. While the days of heavy industry have largely passed, the spirit of that industrious past lingers, evident in the sturdy brick buildings downtown and the pride residents take in their self-reliance. Local events often celebrate this heritage, drawing families together for summer festivals and farmers' markets, a quiet affirmation of the enduring bonds that tie Portland to its land and to each other.
