Saving the best for last, here is a magnificent false-color picture of the Lena River Delta. The Lena, one of the great rivers of the world, rises in the hills a short distance west of Lake Baikal in Siberia, then flows north and east approximately 4400 km (2800 m) and empties into the Laptev Sea about 650 km (400 m) north of the Arctic Circle. The Lena has a drainage area of about 2.5 million square km, or almost a million square miles. 1600KB
