Water resources data for Idaho, water year 1969; Part 2, Water quality records
U.S. Geological Survey
1970, Water Data Report ID-69-2
Water-resources investigations of the U.S. Geological Survey include the collection of water-quality data on the chemical and physical characteristics of surface- and ground-water supplies of the Nation. These data for the 1969 water year for the quality of surface waters in Idaho are presented in this report. Data for a...

Aerial infrared surveys of Reykjanes and Torfajökull thermal areas, Iceland, with a section on cost of exploration surveys
G. Pálmason, J. D. Friedman, R.S. Williams Jr., J. Jonsson, K. Saemundsson
1970, Geothermics (2) 399-412
In 1966 and 1968 aerial infrared surveys were conducted over 10 of 13 high-temperature thermal areas in Iceland. The surveys were made with an airborne scanner system, utilizing radiation in the 4.5–5.5 μm wavelength band.Supplementary ground geological studies were made in the Reykjanes and Torfajökull thermal areas to interpret features...
Sr87/Sr86 ratios of Quaternary lavas of the Cascade Range, northern California
Zell E. Peterman, I. S. E. Carmichael, A. L. Smith
1970, Bulletin of the Geological Society of America (81) 311-317
Quaternary lavas from Mount Lassen, Mount Shasta, and Medicine Lake, which range in composition from olivine basalt to rhyolite, have Sr87/Sr86 values that fall between 0.7030 and 0.7043, corrected to 0.7080 for the Eimcr and Amend (MIT) SrCO3 standard. These values are very close to average (corrected)...
Clay minerals: A guide to their x-ray identification
Dorothy Carroll
1970, Book
This paper is a guide to the X-ray examination of clay minerals; it incorporates background information concerning the principal crystallographic features of clay minerals, and how this is used in the X-ray identification of these minerals, together with laboratory techniques and the application of X-ray diffractometry to the diagnosis of...
Palynology of the Cretaceous-Tertiary boundary in the northern Rocky Mountain and Mississippi Embayment regions
Robert H. Tschudy
Robert M. Kosanke, Aureal T. Cross, editor(s)
1970, Book chapter, Symposium on Palynology of the Late Cretaceous and Early Tertiary
In both the Rocky Mountain and the Mississippi Embayment regions it is often difficult to distinguish Upper Cretaceous from lower Tertiary rocks on the basis of physical characteristics; the transition can be recognized with relative ease, however, on the basis of abrupt qualitative changes in plant microfossils. Many Cretaceous species...
IASH Commission of Snow and Ice meeting: Paris, France, September 3-5, 1969
Mark Frederick Meier
1970, Eos, Transactions, American Geophysical Union (51) 30-30
The IASH Commission of Snow and Ice met jointly with the Working Group on Glaciology of the Special Committee on Antarctic Research (SCAR).Five technical guides have been prepared by the Commission of Snow and Ice for major IHD projects and have been in press at Unesco for more than a...
On the theory of evolution of river nets
A. E. Scheidegger
1970, International Association of Scientific Hydrology - Bulletin (15) 109-114
An investigation is made of the growth of river basins based on the two current models of the structure of such basins: the cyclic model and the random-graph model. Based on the assumption that the networks grow allometrically, the structure of the network that evolves has...
A brief history of commercial fishing in Lake Erie
Vernon C. Applegate, Harry D. Van Meter
1970, Fishery Leaflet 630
Salient features of the development of the industry from about 1815 to 1968, changes in fishing gears and methods, changes in the kinds and abundance of fishes caught, and the attendant effects of disappearing species on the stability of the fishery are described. The history and present status of the...
