Pick of the pics
Himalayas or fractals?
In this 2002 image, soaring, snow-capped peaks and ridges of the eastern Himalayas create an irregular white-on-red patchwork between major rivers in southwestern China. The Himalayas are made up of three parallel mountain ranges that together extend for more than 2900 kilometers (1800 miles).
