Oslo sits at a sharp oxbow of the Red River of the North, serving as a focal point where the borders of Marshall, Walsh, Polk, and Grand Forks counties converge. This 2016 survey highlights the intricate hydrology of the Red River Valley, where the meandering main channel is fed by the Turtle River and Marais River, alongside an extensive network of engineered drainage like County Ditch Number 13. The settlement of Poland appears to the west, situated within a strictly gridded agricultural landscape defined by roads like Co Hwy 19 and 54th St NE. Local heritage is anchored by the Riverside Cem and Saint Joseph Cem, which stand near the river's edge, reflecting the enduring community footprints in this fertile borderland between Minnesota and North Dakota.
