Major Texas floods of 1936
Tate Dalrymple
1947, Water Supply Paper 816
In 1936 floods occurred in parts of Texas during two periods one about July 1 and the other in the later portion of September which were marked by record-breaking or outstanding stages and discharges on some of the larger rivers.  ...
Suspended sediment in the Colorado River, 1925-41
Charles S. Howard
1947, Water Supply Paper 998
This report gives the results of sediment-sampling studies of the Geological Survey in the Colorado River basin for the period from October 1, 1925, to September 30, 1941. Records are given for the entire period for the Grand Canyon gaging station and for shorter periods at other stations in the...
Results of varying the ratio of largemouth black bass and bluegills in the stocking of experimental farm ponds
E. W. Surber
1947, Transactions of the American Fisheries Society (77) 141-151
During the period 1943 to 1946, several combinations of largemouth black bass (Micropterus salmoides) and bluegill (Lepomis macrochirus) were stocked in ponds on the station grounds at Leetown, West Virginia. These ponds were fertilized with 12–5–5, inorganic fertilizer, but when water blooms failed to control the submerged vegetation, sodium...
Preliminary report on stratigraphy and structure of the area of the Colville River north of Umiat, Alaska
Karl Stefansson, R. F. Thurrell Jr., J. H. Zumberge
1947, Geological Investigations, Naval Petroleum Reserve No. 4, Alaska 13
The stratigraphy and structure of the area of the Colville north of Umiat was studied by U. S. GeologicaI Survey Party No. 1 during the period of May 31 to July 19, 1947. The. party, consisting pf two geologists, a cook, and a "weasel" mechanic, left Umiat in two "weasels”....
Part 3: Volcano investigations on Umnak Island, 1946
F. M. Byers Jr., D.M. Hopkins, K. L. Wier, Bernard Fisher
1947, Report, Alaskan Volcano Investigations Report No. 2
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...
Thrust faults and related structures in eastern Cuba
T. P. Thayer, P. W. Guild
1947, Eos, Transactions, American Geophysical Union (28) 919-930
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...
Chemical analyses and calculated modes of the Oliverian magma series, Mt. Washington Quadrangle, New Hampshire 
M.P. Billings, J.C. Rabbitt
1947, GSA Bulletin (58) 573-596
Complete chemical analyses, including the spectrographic determination of 44 trace elements, have been made of six representative specimens from each of the six map units constituting the Oliverian magma series in the Mt. Washington quadrangle of New Hampshire. Potash is systematically higher than soda. An increase in silica, which ranges...
Geology of the Borah Peak quadrangle, Idaho 
C. P. Ross
1947, GSA Bulletin (58) 1085-1160
This report is on result of a long program of geologic investigation in south-central Idaho, undertaken as an aid in the development of the mineral resources of the region. This quadrangle was examined because of the exceptional opportunities for the study of stratigraphy and structure afforded by the Lost River...
Suggestions as to future research in ground‐water hydrology
O. E. Meinzer
1947, Eos, Transactions, American Geophysical Union (28) 418-420
Determination of the ground‐water supply available from any aquifer or in any specified area requires not merely the application of specific quantitative methods but also a broad and accurate knowledge of the geologic, hydrologlc, and geochemical factors that are involved, and consideration of the economic and legal limitations. Further research...
Ground-water conditions and problems in the Upper Mississippi River Embayment
Robert Schneider
1947, Economic Geology (42) 626-633
The Upper Mississippi River Embayment is a region of about 45,000 square miles in the Mississippi River Valley extending from the vicinity of the 34th parallel northward to the mouth of the Ohio River. It includes parts of Arkansas, Mississippi, Tennessee, Kentucky, and Missouri. In 1940 about 2,700,000 people inhabited...
Geology and ground-water resources of Puerto Rico
Charles Lee McGuinness
1947, Economic Geology (42) 563-571
Puerto Rico, the easternmost and smallest of the Greater Antilles, has an axis of deformed and metamorphosed volcanic rocks of Upper Cretaceous age, intruded by dioritic rocks during the Antillean revolution. The hard-rock core is flanked on the north and south by limestones and clastic rocks of late Oligocene and...
