Geology of Massachusetts and Rhode Island

In preparing the present treatise and the accompanying geologic map of Massachusetts and Rhode Island (PI. X, in pocket) I have endeavored to use all the material available. The matter has been greatly condensed, for the detailed geology of a considerable part of the area will be described in a number of forthcoming folios of the Geologic Atlas of the United States. The Holyoke folio, published in 1898, covered the major part of the Triassic rocks in Massachusetts, but as those rocks have since been more thoroughly studied they are here treated in greater detail to bring their discussion up to date.

Chattanooga Folio, Tennessee

The Geological Survey is making a large topographic map and a large geologic map of the United States, which are being issued together in the form of a Geologic Atlas. The parts of the atlas are called folios. Each folio contains a topographic map and a geologic map of a small section of country, and is accompanied by explanatory and descriptive texts. The complete atlas will comprise several thousand folios.

Geology of the Calamity Mesa quadrangle, Colorado

The series of Geologic Quadrangle Maps of the United States continues the series of quadrangle maps begun with the folios of the Geologic Atlas of the United States, which were published from 1894 to 1945. The present series consists of geologic maps, supplemented where possible by structure sections, columnar sections, and other graphic means of presenting geologic data, and accompanied by a brief explanatory text to make the maps useful for general scientific and economic purposes. Full description and interpretation of the geology of the areas shown on these maps are reserved for publication in other channels, such as the Bulletins and Professional Papers of the Geological Survey. Separate maps of the same areas, covering bedrock, surficial, engineering, and other phases of geology, may be published in the geologic quadrangle map series.

Hartville folio, Wyoming

The Geological Survey is making a geologic map of the United States, which necessitates the preparation of a topographic bas map. The two are being issue together in the form of an atlas, the parts of which are called folios. Each folio consists of a topographic base map and geologic maps of a small area of country, together with explanatory and descriptive texts.

Yellowstone National Park folio, Wyoming

The area covered by the maps of the Yellowstone National Park folio is represented upon four atlas sheets, known as the Gallatin, Canyon, Lake, and Shoshone sheets, and is embraced between the parallels of 44° and 45° north latitude and the meridians of 110° and 111°. It is situated in the northwest corner of the State of Wyoming, and includes 3,412 square miles.

Pocahontas folio, Virginia-West Virginia

The territory represented by the Pocahontas atlas sheet is one-quater of a square degree of the earth's surface, extending from latitude 37° on the south to 37° 30' on the north, and from longitude 81° on the east to 81° 30' on the west. Its average width is 27.5 miles, its length 34.5 miles, and its area 951 square miles.

Newcastle folio, Wyoming-South Dakota

The Newcastle quadrangle embraces the quarter of a square degree which lies between parallels 43° 30' and 44° north latitude and meridians 104° and 104° 30' west longitude. It measures approximately 34 1/2 miles from north to south and 25 1/8 from east to west, and its area is 863 4/5 square miles. It lies mainly in the eastern portion of Weston County, Wyo., but includes also a narrow area of western Custer and Pennington counties, S. Dak. The northeastern portion of the quadrangle lies on the slopes of the Black Hills, but the larger part of it belongs to the Great Plains, although these plains are lower here than in the greater part of adjoining portions of Nebraska and Wyoming. The district is drained by branches of the South Branch of Cheyenne River.

Cottonwood Falls folio, Kansas

The Cottonwood Falls quadrangle lies between parallels 38° and 38° 30' and meridians 96° 30' and 97°, and therefore constitutes a quarter of a square degree of the earth's surface. It is 34.35 miles long and 26.75 miles wide, and contains about 938 square miles. It is located east and a little south of the central part of Kansas, on Cottonwood River, and includes large portions of Chase and Marion counties and small portions of Greenwood and Butler counties.
