Geologic map of the Lone Pine 15' quadrangle, Inyo County, California Geologic map of the Lone Pine 15' quadrangle, Inyo County, California
Oblique aerial view west across Owens Valley in Lone Pine 15' quadrangle. In distance, Sierra Nevada, capped by Mount Whitney (elev. 14,494 ft; 4,418 m). In middle distance, Alabama Hills, town of Lone Pine, and Owens River. In foreground, Kern Knob, at base of Inyo Mountains. Movement along Owens Valley Fault Zone, at base of Alabama Hills, caused great Lone Pine earthquake of 1872...
Geology of the Cape MendocinoGeology of the Cape Mendocino, Eureka, Garberville, and southwestern part of the Hayfork 30 x 60 minute quadrangles and adjacent offshore area, northern California, with digital database Geology of the Cape MendocinoGeology of the Cape Mendocino, Eureka, Garberville, and southwestern part of the Hayfork 30 x 60 minute quadrangles and adjacent offshore area, northern California, with digital database
Introduction These geologic maps and accompanying structure sections depict the geology and structure of much of northwestern California and the adjacent continental margin. The map area includes the Mendocino triple junction, which is the juncture of the North American continental plate with two plates of the Pacific ocean basin. The map area also encompasses major geographic and...
Lithologic, age group, magnetopolarity, and geochemical maps of the Springerville Volcanic Field, east-central Arizona Lithologic, age group, magnetopolarity, and geochemical maps of the Springerville Volcanic Field, east-central Arizona
The Springerville volcanic field is one of the many late Pliocene to Holocene, mostly basaltic, volcanic fields present near the Colorado Plateau margin (fig. 1, in pamphlet). The field overlies the lithospheric transition zone between the Colorado Plateau and the Basin and Range Province (Condit and others, 1989b). Establishing relations in time, space, and composition of the rocks of...
Geologic map of the Mohave Mountains area, Mohave County, western Arizona Geologic map of the Mohave Mountains area, Mohave County, western Arizona
Introduction The Mohave Mountains area surrounds Lake Havasu City, Arizona, in the Basin and Range physiographic province. The Mohave Mountains and the Aubrey Hills form two northwest-trending ranges adjacent to Lake Havasu (elevation 132 m; 448 ft) on the Colorado River. The low Buck Mountains lie northeast of the Mohave Mountains in the alluviated valley of Dutch Flat. Lowlands at...
Geologic map of the western part of the Cut Bank 1° x 2° quadrangle, northwestern Montana Geologic map of the western part of the Cut Bank 1° x 2° quadrangle, northwestern Montana
The paper geologic map of the western part of the Cut Bank 1° x 2° quadrangle, northwestern Montana (Harrison and others, 1998) was digitized and initially attributed by the Montana Bureau of Mines and Geology (MBMG) and remitted to the U.S. Geological Survey for further attribution and publication of the geospatial digital files. The resulting digital geologic map GIS can be queried in...
Quaternary geologic map of the Ozark Plateau 4° x 6° quadrangle, United States Quaternary geologic map of the Ozark Plateau 4° x 6° quadrangle, United States
The Quaternary Geologic Map of the Ozark Plateau 4° x 6° Quadrangle was mapped as part of the Quaternary Geologic Atlas of the United States. The atlas was begun as an effort to depict the areal distribution of surficial geologic deposits and other materials that accumulated or formed during the past 2+ million years, the period that includes all activities of the human species. These...
Quaternary geologic map of the Blue Ridge 4° x 6° quadrangle, United States Quaternary geologic map of the Blue Ridge 4° x 6° quadrangle, United States
This map is part of the Quaternary Geologic Atlas of the United States (I-1420). It was first published as a printed edition in 1986. The geologic data have now been captured digitally and are presented here along with images of the printed map sheet and component parts as PDF files. The Quaternary Geologic Map of the Blue Ridge 4° x 6° Quadrangle was mapped as part of the Quaternary...
