How to read this map
The Rainy River is about 140 km (87 mi) long. It rises at Rainy Lake and flows into Lake of the Woods. It flows through or along the United States and Canada. Tributaries include Baudette River, Big Fork River and Little Fork River.
The highlighted blue line is the course of the Rainy River as mapped by Natural Earth. Towns and cities on the map include Thunder Bay.
Greens show lower elevations; tan and brown show higher land, with pale tones toward the highest terrain. Shadows emphasize the slopes, and vertical relief is exaggerated so landforms are easier to read. Dashed lines show country borders, and fine dashed lines show state or province borders.
The relief uses Terrain Tiles (SRTM, GMTED2010 and ETOPO1 elevation data). Rivers, lakes, borders and the course of the Rainy River come from Natural Earth, and the figures on this page from Wikidata. Natural Earth draws features at a small scale, so the line is a guide to where the Rainy River is, not a surveyed boundary.
