The agricultural plains of Polk County are defined by the winding course of the Red Lake River and the meandering Grand Marais Creek. This 2022 survey captures the southeastern expansion of East Grand Forks, where residential streets like 10th St SE and 17th Ave SE meet the riparian corridor. Further southeast, the small settlement of Mallory sits at the junction of Co Rd 66 and 200th St SW, serving as a local node in a landscape dominated by a precise section-line grid of rural roads.
