Development of photogrammetry in the U.S. Geological Survey
Morris M. Thompson
1958, Circular 218
Photogrammetry, the science or art of obtaining reliable measurements by means of photography, is now used extensively in topographic mapping. Precise photogrammetric plotting instruments now enable the map maker to extract from aerial photographs much.of the detailed information required for drawing the map that formerly was acquired by laborious ground...
Geology and ore deposits of the Jerome area, Yavapai County, Arizona
C.A. Anderson, S.C. Creasey
1958, Professional Paper 308
The Jerome area, in central Arizona, includes the Mingus Mountain quadrangle and parts of the adjacent Clarkdale, Mayer, and Mount Union quadrangles. The largest copper mines in the area at Jerome are the United Verde Extension and the United Verde. The United Verde Extension, closed in 1938 and the United...
Reconnaissance petrography of the Idaho batholith in Valley County, Idaho
Dwight Lyman Schmidt
1958, Open-File Report 58-89
The purpose of this report is to describe the rocks comprising a part of the Idaho batholith in west-central Idaho (see index map, Figure 1). The study is a by-product of an investigation of placer deposits containing radioactive minerals, monazite and euxenite, by the U. S. Geological Survey on behalf...
Hydraulic and hydrologic aspects of flood-plain planning
Sulo Werner Wiitala, Karl R. Jetter, Alan J. Sommerville
1958, Open-File Report 58-109
The valid incentives compelling occupation of the flood plain, up to and even into the stream channel, undoubtedly have contributed greatly to the development of the country. But the result has been a heritage of flood disaster, suffering, and enormous costs.Flood destruction awakened a consciousness toward reduction and elimination of...
Origin of manganese deposits of Busuanga Island, Philippines
Ronald Keith Sorem
1958, Open-File Report 58-98
The manganese deposits of Busuanga Island, Palawan, are tabular and broadly lenticular bodies which lie conformably within a thick sequence of deformed abort beds. The purpose of this study is to determine the probable mode of origin of the deposits. Similar deposits in other parts of the world have been...
Geology of the Little Commonwealth area, Florence County, Wisconsin
Robert William Johnson Jr.
1958, Open-File Report 58-53
The Little Commonwealth exploration in northeastern Florence County, Wisconsin, is underlain by highly ferruginous clastic rocks that are stratigraphically equivalent to vitreous quartzite. The relationship between these rocks is one of abrupt facies change, with complete gradation between facies. This stratigraphic unit is conformably underlain by sericitic phyllite and unconformably...
The geology and ore deposits of Upper Mayflower Gulch, Summit County, Colorado
John Alexander Randall
1958, Open-File Report 58-79
Upper Mayflower Gulch is on the highly glaciated western side of the Tenmile Range near Kokomo in central Colorado. Somewhat less than $500,000 in silver and gold has been produced from the area since the first mining in the 1880' s. In the mapped area high grade regional metamorphism has...
Periodic heat flow in a stratified medium with application to permafrost problems
Arthur H. Lachenbruch
1958, Open-File Report 58-57
Solutions to the Fourier heat equation for quasi-steady periodic flow in a stratified semi-infinite medium can be obtained readily by standard methods. The results have wide application to studies of earth-temperature variations induced by diurnal, annual, and other periodic variations in ground surface temperature. Much of the previous work on...
Regional gravity survey of the Carrizo Mountains area, Arizona and New Mexico
Donald Plouff
1958, Open-File Report 58-76
A total of 570 gravity stations were established within an area of about 1,000 square miles south of the common corner of Colorado, Utah, Arizona, and New Mexico. The Bouguer gravity anomaly pattern apparently is unrelated to the disposition of minette plugs inasmuch as there probably is little contrast in...
Rate for flood insurance
Walter Basil Langbein
1958, Open-File Report 58-60
Soon after the 1951 floods on the Kansas and lower Missouri Rivers, President Truman submitted to Congress (82d Cong., 1st sess., 1951) a proposal for a national flood insurance fund. Although the proposal was not acted upon by the 82d Congree, there was considerable discussion of it in the press...
