St. Marys River Map
St. Marys River is a lake across Canada and the United States. This map shows the lake outlined in blue on shaded relief, with the rivers, borders and towns around it.
How to read this map
It lies in Michigan.
The blue outline marks St. Marys River as mapped by Natural Earth. Towns and cities on the map include Sault Ste. Marie and Petoskey.
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 outline of St. Marys River come from Natural Earth, and the figures on this page from Wikidata. Natural Earth draws features at a small scale, so the outline is a guide to where St. Marys River is, not a surveyed boundary.
