Map showing ground-water conditions in the Bodaway Mesa area, Coconino County, Arizona: 1977
C. D. Farrar
1979, Open-File Report 79-1488
The Bodaway Mesa area includes about 800 square miles in north-central Arizona, and most of the area is in the Navajo Indian Reservation. Ground-water development has been slight; in 1977 the estimated ground-water withdrawal was less than 5 acre-feet. The Chinle Formation is the principal aquifer tapped by wells, and...

1979, Circular 805
Resources were assessed for thorium in the higher grade and better known deposits in the United States in: (1) veins, (2) massive carbonatites, (3) stream placers of North and South Carolina, and (4) disseminated deposits. Thorium resources for the first three categories were divided into reserves and probable potential resources....

Ground-water availability in parts of the Chicopee and Mill River basins, near Wilbraham, Massachusetts
David F. Delaney
1979, Water-Resources Investigations Report 79-72
Ground water in the Wilbraham area occurs in glacial drift and in underlying bedrock. Stratified sand and gravel deposits form the principal unconsolidated aquifers. These aquifers are generally less than 50 feet thick in most of the study area; however, an area in north-central Wilbraham, near the Chicopee River, is...
Map showing occurrences of spring-deposited travertine in the conterminous Western United States
J. H. Feth, Ivan Barnes
1979, Water-Resources Investigations Report 79-35
Extinct travertine terraces occur hundreds of meters above present levels of spring activity and have potentials for interpretation of ancient hydrologic systems, rates of downcutting, or rates of tectonic uplift that remain virtually unexploited. The abundance and size of extinct travertine deposits suggest that in many places, such as pinnacles...
Aeromagnetic map and associated depth map of the Upper Mississippi Embayment region

1979, Miscellaneous Field Studies Map 1158
The purpose of these maps is to present recently compiled aeromagnetic data and associated depth estimates to magnetic basement in the upper Mississippi embayment region. This area is one of the most seismically active regions in the eastern United States. In 1974, the U.S. Geological Survey initiated magnetic surveys to...
