The Ob River runs a course through the middle of Russia's largest and most important gas and oil region. The West Siberian Basin, a vast region of tundra and taiga in north-central Russia, contributes about two-thirds of the country's crude oil and natural gas output. This image features oil fields near the confluence of the Irtysh River (lower left) and Ob River (running horizontally through center of image). The oil-drilling operations appear as a network of scattered gray dots against the green and brown landscape. In the floodplains and stream valleys, forests (green) dominate, whereas fall weather has turned vegetation in the bogs, fens, and mires (north and south of the river) brown. Large numbers of lakes (dark blue) are scattered throughout the image. The tendrils of green running through the swampy areas are forests.
