The petroleum fields of the Pacific coast of Alaska, with an account of the Bering River coal deposits

This report contains the result of a hasty examination of the structural and economic geology of the localities where indications of petroleum have been found. Though only a few wells have been drilled and it is too soon to predict an important future for the region as a petroleum producer, studies have shown that there is ample justification for further prospecting and that the region may yet be

The southern Appalachian forests

In examining so large an area it was found that the best results could be obtained by traversing the roads and trails and making side trips wherever necessary to cover intermediate territory. Upon the topographic maps of the Geological Survey were drawn the outlines of cleared land and the several classes of forest land as they were passed. At the same time ocular estimates of the average stand an

The Triassic cephalopod genera of America

The marine Triassic section of .America is unusually complete, and its thickness compares favorably with that of any other region. All three subdivisions-Lower, Middle, and Upper Triassic--are represented by calcareous deposits, aggregating approximately 4,000 feet in thickness. Of this amount, about 800 feet belong to the Lower Triassic, about 1,000 feet to the Middle Triassic, and about 2,000 fe

IntroductionRemarks on the work of the yearBranches of workThe United States Geological Survey was created in 1879 for the purpose—as its name implies—of examining and reporting on the geologic structure and mineral resources and products of the national domain. To the adequate description of geologic formations and structure cartography is essential, and Congress early recognized this fact by mak
