Geology and ore deposits of the Casto quadrangle, Idaho
Clyde P. Ross
1934, Bulletin 854
The study of the Casto quadrangle was undertaken as the first item in a project to obtain more thorough knowledge of the general geology of southcentral Idaho on which to base study of the ore deposits of t he region. The quadrangle conta ins fragmentary exposures of Algonkian and Paleozoic...
Artesian water in Somervell County, Texas
Albert George Fiedler
1934, Water Supply Paper 660
Somervell County is part of the Grand Prairie region of north-central Texas. An excellent supply of artesian water is available from the Trinity reservoir at no great depth. The first flowing well in Somervell County was drilled in 1880, and the first flowing well in Glen Rose, the county seat,...
Ground-water supplies and irrigation in San Pedro Valley, Arizona
Kirk Bryan, G. E. P. Smith, Gerald A. Waring
1934, Open-File Report 67-31
The San Pedro Valley in southeastern Arizona extends from the International Boundary northward about 120 miles to the junction of the San Pedro River with the Gila River.  The river basin also extends about 75 miles into Mexico.  The valley varies in width from 5 to 20 miles, being widest...
The McCoy mining district and gold veins in Horse Canyon, Lander County, Nevada
Frank Charles Schrader
1934, Circular 10
The following geologic sketch is based on a two-day visit made to the McCoy district in September 1930. For valuable information and aid generously extended, the writer would express his thanks to the miners and prospectors of the district and especially to Mr. Joseph H. McCoy, a well-known mining man...
Fifty-fifth annual report of the Director of the Geological Survey

1934, Annual Report 55
From the point of view of the geologists of this continent, the important event of the year was the meeting in Washington, in July, of the sixteenth session of the International Geological Congress.  The only other session held in the United States was the fifth, in 1891....
Field evidence about the viscosity of lavas
Clarence S. Ross
1934, Eos, Transactions, American Geophysical Union (15) 255-257
There appears to be surprisingly little definite information on the viscosity of lavas. With few exceptions writers content themselves with such general and indefinite terms as “mobile”, “viscous”, or “highly viscous”. Apparently the only attempts to actually calculate viscosity have been made on Hawaiian lavas.  ...
The Rôle of volatiles in the formation of Virginia titanium deposits
C. S. Ross
1934, Eos, Transactions, American Geophysical Union (15) 245-245
The feldspathic rock with which the titanium deposits of Virginia are associated appears to be an anorthosite, although the plagioclase is somewhat more sodic than in normal anorthosites. That is, this rock shows evidence of having been introduced as a mush‐like mass of crystals and intersititial magma, and of undergoing...
Relation of stream‐flow to ground‐water levels
L.L. Harrold
1934, Eos, Transactions, American Geophysical Union (15) 414-416
In recent years the Water Resources Branch of the United States Geological Surrey has given considerable attention to the relation of ground‐water to stream‐flow. One locality in which this relation is being studied is about 13 miles from Washington, near Colesvllle, Maryland, where a Kinnison float‐gage is being maintained in a well In connection with the operation of a...
