How to read this map
The Snake River is about 1,740 km (1,080 mi) long and drains a basin of about 278,000 km² (108,000 sq mi). Its average discharge is about 1,550 m³/s (54,700 cu ft/s). It rises at Yellowstone National Park and flows into the Columbia River. It flows through or along Washington, Idaho, Oregon and Wyoming. Tributaries include Owyhee River, Malheur River, Powder River, Heart River, Boise River, Salmon River, Clearwater River and Raft River.
The highlighted blue line is the course of the Snake River as mapped by Natural Earth. Towns and cities on the map include Idaho Falls, Pocatello, Twin Falls and Burley.
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 Snake 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 Snake River is, not a surveyed boundary.
