How to read this map
The Erg Chech is about 206,000 km² (79,500 sq mi) in area. It extends across Algeria, Mali and Mauritania. Its typical elevation is about 307 m (1,007 ft).
The dashed outline marks the Erg Chech as mapped by Natural Earth. Towns and cities on the map include Adrar.
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.
The relief uses Terrain Tiles (SRTM, GMTED2010 and ETOPO1 elevation data). Rivers, lakes, borders and the outline of the Erg Chech 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 Erg Chech is, not a surveyed boundary.
