Theoverthrust belt of western North America extends from British Columbiato southern Nevada. Large anticlines lie on thrust sheets alongthe length of this overthrust trend. Many oil and gasfields have been discovered on these structures in Canada, butsignificant hydrocarbon production in the United States has been primarilylimited to a productive salient in southwestern Wyoming and northeasternUtah (Figure 1).
