The settlement of Portland sits at the northern edge of this Iowa landscape, where the Winnebago River snakes through the terrain near the junction of Little Gully and Big Gully. The map illustrates a highly structured rural grid defined by roads such as Ulmus Ave and Warbler Ave, punctuated by the winding paths of several waterways including Rock Creek and Rapid Creek. A notable genealogical landmark, the Owen's Grove Cem, is located south of Portland along 220th St.
