Sumatra, Indonesia - March 27th, 2009

Sumatra (also spelled Sumatera) is the largest island completely in western Indonesia. The interior of the island is dominated by two geographical regions: the Barisan Mountains in the west and swampy plains in the east.

In this eastern region, big rivers carry silt from the mountain, forming the vast lowland interspersed by swamps. Here, several rivers pour dark and light brown sediments into the sea, south of the Lingga Islands.

Even if mostly unsuitable for farming, the area is currently of great economic importance for Indonesia. It produces oil from both above and below the soil—palm oil and petroleum.
