How to read this map

The Gulf of Saint Lawrence covers about 226,000 km² (87,300 sq mi) and reaches a maximum depth of about 530 m (1,739 ft). Countries with a coast on the Gulf of Saint Lawrence: Canada.

The blue outline marks the Gulf of Saint Lawrence as mapped by Natural Earth. Towns and cities on the map include Halifax, St. John's, Moncton, Saint John, Fredericton and Bangor. Labeled states and countries: Maine, New Brunswick, Nova Scotia and Prince Edward Island.

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 the Gulf of Saint Lawrence 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 the Gulf of Saint Lawrence is, not a surveyed boundary.
