Yesterday we came across this really cool photo gallery of rivers seen from space on Wired. These images — taken both from satellites and by astronauts — are simply stunning. In many cases they look much more like strange abstract paintings than aerial photos of nature. That’s why after the jump we’re challenging the geography nerds in our audience to correctly ID five of our favorites. Highlight the black boxes to find out if you’re right.
1. Mississippi River
2. Ganges River, India
3. San Juan River, Colorado
4. Nile River, Egypt
5. Niagara Falls
