How to read this map
The Thelon River is about 904 km (562 mi) long and drains a basin of about 142,000 km² (55,000 sq mi). Its average discharge is about 840 m³/s (29,700 cu ft/s). It rises at Whitefish Lake and flows into Baker Lake. Tributaries include Dubawnt River, Hanbury River, Mary Frances River, Tammarvi River, Kigarvi River, Finnie River and Clarke River.
The highlighted blue line is the course of the Thelon River as mapped by Natural Earth. Labeled countries: Nunavut.
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 Thelon 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 Thelon River is, not a surveyed boundary.
