Geological Survey Party 4 began studies at a point on the Colville River 18 miles downstream from the mouth of the Killik River on July 19. From this point the studies were continued along the Colville River to near the mouth of Prince Creek. The investigation was completed on September 1 and the party returned to Umiat. A traverse was made along the lower half of Prince Creek and along one of its

During the summer of. 1947, U. S. Geological Survey Party No. 2 made a reconnaissance survey of the area between Awuna River and the divide north of the Kigalik River. The westernmost observations were made along the Awuna anticline to longitude about 157°30' W. and along the Kigalik anticline to longitude about 156°55'W. The easternmost work was done along the Knife Blade Ridge anticline at a lon

During the summer of 1946 the United States Geological Survey continued its program of stratigraphic and structural investigations in Naval Petroleum Reserve No. 4, northern Alaska. This report summarizes the results of work in the area of Maybe Creek (see inset, fig. 1). The area studied is southwest of Umiat and includes about 500 square miles lying generally between the headwaters and mouth of

The Noonan quadrangle is in northwestern North Dakota adjacent to the Dominion of Canada and approximately 35 miles east of Montana. The small coal-mining, farm, and railroad town of Noonan is located near the eastern edge of this sparsely populated area. The east-west State Highway 5 bisects the quadrangle.Cultural development in this area depends largely on agricultural exploitation of the glaci

The delineation of parallel folds in structural sections, and the extraction therefrom of stratigraphic information, has generally been done with considerable personal interpretation. If profiles must be drawn, or sections measured, from structural observations used in pairs, this is unavoidable; but superior results may be obtained if more than two observations are simultaneously utilized. The fi

This report incorporates the results of field and. laboratory studies, from June 1946 through March 1947, of the stratigraphy and. structure of the area of the Meade and Kuk Rivers and Point Barrow, Alaska. The Investigations were made by the Geological Survey as part of the Navy Department's program of petroleum exploration in northern Alaska.

The area between 68° 3C' and 69° 08 N. latitude and between 154° and 155° 20 W. longitude was covered by U. S. Geological Survey party 4 during the period May 18 to September 2. Traverses were confined mainly to the valleys of the Kurupa, Oolamnagavik, and Colville Rivers inasmuch as very little rock is exposed in the interstream areas. This report is a compilation of the field data and of the res

Umnak Island is a dumbbell-shaped island in the eastern part of the Aleutian Islands. The island is 70 miles long and trends northeast-southwest. During 1946 volcano investigations were begun on the island and geologic mapping of most of northeastern Umnak Island was completed.Okmok Volcano, a large, broad volcanic mountain rising to altitudes of 3,000 to 3,500 feet, occupies the central portion o

Geological Survey Party No. 4 was assigned an investigation of the Ikpikpuk and Titaluk Rivers and East Fork of the Ikpikpuk River mainly for the purpose of obtaining stratigraphic information which would be of use in determining the parts of the Upper Cretaceous sequence that underlie the areas investigated by United Geophysical Company parties 43 and 46.A total of five days were spent in geologi

U.S. Geological Survey Party 3 studied the geology of the Utukok River area and conducted a short reconnaissance of the Corwin-Cape Beaufort Region during the period May 12 to August 31, 1947. The upper part of the Utukok River was examined for several miles on either side while the lower, or Coastal Plain-portion, was necessarily limited to the few outcrops along the river.During this study, the

Detailed areal mapping in central Camagüey Province and reconnaissance mapping in northern and eastern Oriente Province, Cuba, have revealed two major structural zones: (1) A zone of intense deformation, including thrust faulting, which lies north of the geographic axis of the island; and (2) a belt of domical mountains bounded on the north by Nipe Bay and the coast, and on the south by the Cauto
