Stretching across 800,000 square kilometers (300,000 square miles), Namibia contains an array of extreme landscapes: mighty sand dunes, gravel plains, rolling hills, and diamond-rich coastal deserts.
The image above shows the convergence of two contrasting geologic regions near the town of Mariental in south-central Namibia.

The image was acquired on May 9, 2020, by the Operational Land Imager (OLI) on Landsat 8.
