1972, Report
The U.S. Geological Survey collected 110 water samples from Amchitka Island, Alaska, between January 13 and April 5, 1972. Tritium determinations were made on all samples collected and gross alpha and gross beta/gamma determinations were made on 92 samples. The gross alpha and gross beta determinations when compared with previously...

1972, Wisconsin Geological & Natural History Survey Information Circular 21
This report supplements the Wisconsin Geological and Natural History Survey, Information Circular No.9, "Trends in Ground-Water Levels in Wisconsin through 1966". It describes, by hydrographs, the ground-water level trends in Wisconsin for the period 1967-1971. All current observation wells with more than three years of record are included; records of...

1972, Wisconsin Geological & Natural History Survey Information Circular 22
Ground water, a plentiful and largely underdeveloped resource of Wisconsin, has good to excellent chemical quality in most places. This resource is readily available in most parts of the State for municipal, industrial, and rural uses. In 1970, about 0.5 billion gallons of ground water a day was pumped in...

Lehigh County occupies an area of 347 square miles in southeastern Pennsylvania. The northern part of Lehigh County is underlain by the Martinsburg Formation, which consists chiefly of shale and slate. The central part of the county, where most of the population centers are located and much of the urbanization...

The Martinsburg Formation underlies the northern half of Lehigh and Northampton Counties, and is of Middle and LateOrdovician age. It is bounded on the south by older Ordovician limestone formations and on the north by a ridge-forming conglomerate of Silurian age. Recent mapping has supported a three-part division of the...

Four evaporite-bearing stratigraphic zones are known in Cretaceous strata of the Cordillera Oriental of Colombia north and east of Bogota. The easternmost and oldest zone is probably of Berriasian to Valanginian age. The next oldest is probably late Barremian to early Aptian in age. The third appears to be Aptian....

A geochemical exploration program aimed at determining regional patterns of metal distribution as well as pinpointing areas likely to contain undiscovered ore deposits was carried out in north-central Okanogan County, Washington. About 1,000 gully and stream sediment samples were collected from a rectangular area of about 800 square miles. The...

Water-rights problems have occurred in the central Virgin River basin and are expected to increase as development of the water resources increases. The Utah State Engineer needs a basic knowledge of ground-water conditions and of the relation of ground water to surface water as a first step to understanding and...

1972, Book chapter, Apollo 16 preliminary science report (NASA SP 315)
The metric and panoramic cameras aboard the Apollo 16 spacecraft provided photographs on which photogrammetric techniques may be used to obtain precise measurements of horizontal distances and elevations. These measurements of horizontal distances and elevations. These measurements may in turn be used to obtain slope-frequency distributions of lunar surfaces at...

1972, Book chapter, Apollo 16 preliminary science report (NASA SP 315)
The Apollo 15 and 16 metric and panoramic cameras have provided photographs for accurate topographic portrayal of the lunar surface using photogrammetric methods. In turn, quantitative morphologic analyses of topographic results are invaluable aids in the interpretation of the geologic processes....

Heiligenschein is the upsurge in reflected brightness as zero-phase angle is approached. For the first time, an effort has been made to investigate the diagnostic value of the heiligenschein photometric magnitude on a statistically significant scale. This investigation was performed by using the vertical photography of the Apollo 16 metric...

1972, Book chapter, Apollo 16 preliminary science report (NASA SP 315)
Orbital and surface photography collected during the Apollo 16 mission can be used to calibrate existing Earth-based, high-resolution radar maps of the lunar surface. The absence of any theoretical treatment of the radar backscatter from irregular rocks has prevented the assignment of radar-echo cross sections to specific size distributions of...

1972, Book chapter, Apollo 16 preliminary science report (NASA SP 315)
The purpose of the infrared (IR) and radar study of the Apollo data is to establish lunar surface conditions in the vicinity of the orbital tracks of the Apollo command modules during the J-series missions. Correlations and comparisons between the Earth-based radar observations, IR observations, and other data will be...

Low-relief mare features such as ridges and arches are best studied by using stereoscopic photographs taken at low Sun angles. Apollo 16 metric camera photography of the southern Oceanus Procellarum east of Letronne Crater reveals a diversity of subtle features (fig. 29-125) and adds significantly to an understanding of the...

Morphometric analysis of lunar craters (ref. 29-75) complements the more traditional photointerpretive study of crater morphology. These two indirect approaches to the scientific investigation of lunar craters continue to be productive because the preferred alternative method, direct field examination of specific large craters, is not being undertaken in the current...

The Apollo 16 crew photographed an unusual variety of impact craters, including the two craters produced by the impacts of Ranger 7 and 9 spacecraft, small craters produced by boulders as they bounced downslope, craters with marked bilateral symmetry, and primary craters with a wide range of morphologies and sizes....

1972, Book chapter, Apollo 15 preliminary science report (NASA SP-289)
Many Apollo 15 orbital photographs, particularly those taken at low Sun-elevation angles, reveal grid patterns of lineaments. In some circumstances, the grid pattern is present in areas where structural control seems unlikely. For example, in an oblique view (fig. 25-52), the ejecta blankets of two fresh impact craters seem to...

Study of the sinuous Hadley Rille (fig. 25-45) was a primary goal of the Apollo 15 mission. Local geology of the rille near the landing site is described in section 5 of this report. Preliminary study of orbital photography from Hasselblad, metric, and panoramic cameras makes possible a description of...
