Reconnaissance geologic map of the Noatak C5, D5, D6, and D7 quadrangles, Alaska

This map covers the northwestern part of the Noatak 1:250,000-scale quadrangle (fig. 1, sheet 1). The area has low topographic relief that largely consists of gently sloping hills separated by broad expanses of tundra growing on unconsolidated surficial materials. Elevations range from sea level up to 475 m (1,456 ft.) at Mount Jarvis. Study of bedrock geology is constrained by a scarcity of exposures in most areas. Most hill tops are rubble-covered, and there are only a few stream outcrops. As a result many of the stratigraphic and structural relationships between rock units are inferred from similar relationships previously determined in other areas of the western Brooks Range where the rocks are better exposed (Curtis and others, 1982, 1983; Ellersieck and others, 1982, 1983; and Mayfield and others, 1982, 1983 a, b).

Reconnaissance geologic map of the De Long Mountains A1, B1, and part of C1 quadrangles, Alaska

This map is one of a series of three reconnaissance geologic maps of the southern De Long Mountains quadrangle (fig. 1). Because the geology in the three map areas is similar, a composite map explanation has been designed to facilitate their combined use and give a better perspective of the regional geology. There are some rock units and allochthons which do not occur on all three maps. For this reason, the explanation contains more rock units than occur on any one map. Rock units which appear on the accompanying map are indicated by an asterisk beside the map symbol in the explanation.

Reconnaissance geologic map of southwestern Misheguk Mountain quadrangle, Alaska

This map is one of a series of three reconnaissance geologic maps of the southern Misheguk Mountain quadrangle (fig. 1). Because the geology in all three map areas is similar, a composite map explanation has been designed to facilitate their combined use and provide the reader with a better perspective of the regional geology. There are some rock units and allochthons which do not occur on all three maps. For this reason, the explanation contains more rock units than occur on any one map.
