Geology and ground-water conditions of Clark County, Washington, with a description of a major alluvial aquifer along the Columbia River
Maurice John Mundorff
1964, Water Supply Paper 1600
This report presents the results of an investigation of the ground-water resources of the populated parts of Clark County. Yields adequate for irrigation can be obtained from wells inmost farmed areas in Clark County, Wash. The total available supply is sufficient for all foreseeable irrigation developments. In a few local...
Fluvial processes in geomorphology
Luna Bergere Leopold, M. Gordon Wolman, John P. Miller
1964, Book
This excellent text is a pioneering work in the study of landform development under processes associated with running water. Its primary emphasis is on subjects that were the focus of the authors' studies in both field and laboratory. Part I deals with the process of change in the evolving landscape....
Water in the world
Luna Bergere Leopold
1964, The UNESCO Courier (17) 11-13
The earth, Including Its oceans and atmosphere, ls a giant distillation system whose operation brings about the distribution of fresh water throughout the world, from the frozen wastes of polar regions to the burning equatorial deserts. Stated in the simplest terms, distillation, condensation and liquid flow are the elemental processes...
[Book review] Politics and water resources
Luna Bergere Leopold
1964, Science (144) 402-403
Arizona is a state in which development has proceeded sufficiently rapidly relative to the available water supply that its water problems are as acute as those of nearly any other state in the Union. Owing to the fact that, in the past, the principal use of water was for irrigation,...
Classes of land-surface form in the United States
Edwin Hammond
1964, Report, The national atlas of the United States of America
This digital dataset describes classes of land-surface form in the conterminous United States. The source of the data is the map of land-surface form in the 1970 National Atlas of the United States, pages 62-63, which was adapted from Edwin H. Hammond, "Classes of land surface form in the...

The Burnt River valley in southern Baker County, Oreg., is underlain by rocks that range in age from pre-Tertiary to Quaternary. The pre-Tertiary rocks consist mainly of argillites, schists, limestones, and intrusive igneous rocks, while the Tertiary rocks consist mainly of felsic and mafic volcanic tuffs, lava flows and breccias,...
Origin of precambrian iron formations
H. Lepp, S. S. Goldich
1964, Economic Geology (59) 1025-1060
A statistical study of the chemical composition of the Precambrian iron formations of the Canadian Shield affords a new approach to the origin of these unusual formations. The average total iron content of 2,200 samples from the literature and from unpublished mining company analyses is 26.7 percent Fe. The average Fe content for 16 iron formations in the United States and Canada...
