Calcic soils and calcretes in the southwestern United States
George Odell Bachman, Michael N. Machette
1977, Open-File Report 77-794
Secondary calcium carbonate of diverse origins, 'caliche' of many authors, is widespread in the southwestern United States. 'Caliche' includes various carbonates such as calcic soils and products of groundwater cementation. The term 'caliche' is generally avoided in this report in favor of such terms as calcrete, calcic soils, and pervasively...

Geology of the Midnite uranium mine area, Washington — Maps, description, and interpretation
J. Thomas Nash
1977, Open-File Report 77-592
Bedrock geology of about 12 km2 near the Midnite mine has been mapped at the surface, in mine exposures, and from drilling, at scales from 1:600 to 1:12,000 and is presented here at 1:12,000 to provide description of the setting of uranium deposits. Oldest rocks in the area are metapelitic...

Streamflow characteristics of the Joplin area, Missouri
John Skelton
1977, Open-File Report 77-605
Low-flow and peak-flow frequency data and flow-duration-data, based on records from 21 gaging stations in the Joplin area of southwestern Missouri, are presented. Generalized equations and graphs based on gaging-station records are-shown so that estimates of frequency data and the effects of urbanization on peak flows can be made at...
Summary of watershed conditions in the vicinity of Redwood National Park, California
Richard J. Janda
1977, Open-File Report 78-25
The Redwood Creek Unit of Redwood National Park is located in the downstream end of an exceptionally rapidly eroding drainage basin. Spatial distribution and types of erosional landforms, observed in the field and on time-sequential aerial photographs, measured sediment loads, and the lithologic heterogeneity of streambed materials indicated (1) that...
The volumetric properties of vapor-saturated aqueous HCl solutions from 0 degrees to 100 degrees C, vapor-saturated aqueous FeCl2 solutions at 15 degrees and 18 degrees C, and vapor-saturated aqueous FeCl3 from 0 degrees to 35 degrees C based on a regression of the available literature data

Reconnaissance engineering geology of the Metlakatla area, Annette Island, Alaska, with emphasis on evaluation of earthquakes and other geologic hazards
Lynn A. Yehle
1977, Open-File Report 77-272
A program to study the engineering geology of most larger Alaska coastal communities and to evaluate their earthquake and other geologic hazards was started following the 1964 Alaska earthquake; this report about the Metlakatla area, Annette Island, is a product of that program. Field-study methods were of a reconnaissance nature,...

Preliminary data on some Precambrian deposits of zinc-copper-lead sulfides and zinc spinel (granite) in Colorado
Douglas M. Sheridan, William H. Raymond
1977, Open-File Report 77-607
Precambrian sulfide deposits in the Southern Rocky Mountains in Colorado are being studied and re-evaluated according to geologic concepts which were developed in recent years in other parts of the world during successful research regarding economic massive sulfide deposits. These studies, initiated in 1974 in Colorado by the U.S. Geological...

Preliminary report on the coal resources of the Dickinson area, Billings, Dunn, and Stark Counties, North Dakota
Michael L. Menge
1977, Open-File Report 77-482
The Dickinson area is underlain by the coal-bearing Fort Union Formation (Paleocene). The Fort Union in this area contains nine potentially economic coal beds. Five of these beds are, either all or in part, shallow enough to be economically extracted by conventional strip-mining methods, while the remaining four deeper beds...
