Alaska North Slope

The Alaska North Slope is a region of the U.S. state of Alaska. It is on the northern slope of the Brooks Range along the coast of the Arctic Ocean. 
The North Slope is known for having lots of oil. The "National Petroleum Reserve–Alaska" and the "Prudhoe Bay Oil Field" are the two biggest areas where oil is found. The Arctic National Wildlife Refuge is there also, and there has been a lot of debate about drilling for oil there. The oil from the North Slope is pumped south in pipes, called the Trans-Alaska Pipeline System, to Valdez where it is loaded onto ships.
Because the Alaska North Slope is very far north, it gets very cold there. Only the top of the soil, called tundra, melts each season. Because of this, most of the soil is frozen all the time. This frozen soil is called permafrost. On top of the permafrost, water flows in shallow braided streams. Some of it goes into ponds.
