Nebraska is a state in the Great Plains and has many historic trails crossing it. This area was not settled heavily by the Europeans until California's 1848 Gold Rush, when many settlers arrived in the area. Despite the fact that it is now well settled, Nebraska is still one of the least populated states in the United States. Its prairies are vast and treeless, making Nebraska a top state when it comes to the production of cattle. It is also well known for growing pork, soybeans, and corn.
