The maps in the report target five main areas for oil and gas exploration : drilling off the coast of California, Florida and the mid-Atlantic states; drilling in the Rocky Mountain Overthrust Belt and the Alaska North Slope, including ANWR.

If the angle of the fault plane is low ( generally less than 20 degrees from the horizontal ) and the displacement of the overlying block is large ( often in the kilometer range ) the fault is called an " overthrust ".
33.
In 1997, the U . S . Forest Service banned drilling in areas of the Lewis and Clark National Forest that is part of the Overthrust Belt _ a geological formation in Montana, Idaho, Wyoming and northern Utah rich in oil and gas deposits.
34.
The Oil Creek strike is believed to be the result of oil seepage along fault planes in the Lewis Overthrust, in which oil originating in younger Cretaceous rock has moved upwards through older Pre-Cambrian rock that has been forced over the oil-bearing layers.
35.
Both species of " Avisaurus " are known from the humid low-lying swamps, lakes, and river basins of the western shore of the Western Interior Seaway, and from the much more arid uplands between that area and the Cordilleran Overthrust Belt which eventually formed the Rocky Mountains.
36.
Great Northern Mountain ( 8, 705 ft / 2, 653 m ) is the highest peak in the wilderness which is dominated by dozens of other mountains, all part of the Rocky Mountain Front, a huge overthrust fault that spans for 400 miles ( 643 km ) through Canada and Montana.
37.
Physiographically the district, which lies in a region of tectonic or folded and overthrust mountain chains, has strata are structurally marked by complex folds, reverse faults, overthrusts and nappes of great dimensions, all these as well as frequent earthquake of varying intensity give region to believe that the region is still unstable.
38.
During his career he made multiple contributions to the science of geology, including studies of the hydrology of streams, the geology of western Wyoming, seismic energy, mountain building from overthrust faulting, the growth of continents, the origins of the Earth's atmosphere and oceans, and the evolution of terrestrial planets.
39.
In the so-called overthrust belt in the Rocky Mountain states, only 5 percent of 116 million acres of land managed by the Interior Department's Bureau of Land Management _ containing a mere 2 percent of the lower 48's natural gas reserves _ are off limits, either as wilderness or national monuments.
40.
The "'Lewis Overthrust "'is a geologic thrust fault structure of the Rocky Mountains within tectonic plates about 170 million years ago drove a great wedge of rock several miles thick some 50 miles ( 80 km ) eastwards, causing it to overlie softer Cretaceous age rock that is 140 million years younger.
