Two-garnet rodingite from Amador County, California
W. A. Duffield, M.H. Beeson
1973, Journal of Research of the U.S. Geological Survey (1) 665-672
Two distinct phases of garnet have been discovered in rodingite from Amador County, Calif. The two garnets are hydrogrossular and (hydro?) grossular-andradite. Only one, generally hydrogrossular, has been reported in rodingitcs studied by other workers. The rodingite of this study formed from a mafic dike with abundant euhedral plagioclase laths....
Birds imported into the United States in 1971

1973, Special Scientific Report - Wildlife 170
Birds imported into the United States in 1971 are tabulated by species. Total numbers for the period 1968-1971 are given for the more commonly imported taxa. The number of birds imported in 1971 increased only slightly over that for.1970. In 1971, 750 species were imported, of which...

Wolf numbers in the Superior National Forest of Minnesota

1973, Research Paper NC-97
Seventy-seven radio-tagged wolves (Canis lupus), including members of 12 adjacent packs, were located more than 3000 times, and observed on 1337 occasions, from 1968 through mid-1973. Projected population estimates for the 4203 square-mile Forest were 405 plus or minus 20 for winter 1971-72, and 388 plus or minus 14 for...

1973, Book chapter, Environmental Pollution by Pesticides
SUMMARY: Residues of organochlorine pesticides and their breakdown products are present in the tissues of essentially all wild birds throughout the world. These chemicals accumulate in fat from a relatively small environmental exposure. DDE and dieldrin are most prevalent. Others, such as heptachlor epoxide, chlordane, endrin, and benzene hexachloride...

Both State and Federal agencies have been working with the black-footed ferret and prairie dog during the past few years. Much of the work is not extensive enough for publication in scientific journals and is, therefore, not reported. The objective of this Workshop was to bring workers together for discussion...

Ground control requirements for precision processing of ERTS images
Thomas C. Burger
1973, Book
With the successful flight of the ERTS-1 satellite, orbital height images are available for precision processing into products such as 1:1,000,000-scale photomaps and enlargements up to 1:250,000 scale. In order to maintain positional error below 100 meters, control points for the precision processing must be carefully selected, clearly definitive on...
Pleistocene succession of the central interior United States
J.C. Frye
1973, Quaternary Research (3) 275-283
The Quaternary of the continental interior of the United States is characterized by deposits from glacial ice, with associated outwash and eolian deposits, and by alluvial deposits produced by the same climatic pulses. Erosional incision of valleys occurred early in the glacial pulse, outwash deposition during the waning phase of...
Sea level history in Beringia during the past 250,000 years
D.M. Hopkins
1973, Quaternary Research (3) 520-540
This paper attempts to relate current knowledge of sea-level history in Beringia to the Broecker-van Donk “Termination” concept of climatic and sea-level history. The Einahnuhtan transgression is thought to represent Termination III, which according to Broecker and van Donk, took place about 225,000...

On the basis of the newest interpretations of all sufficiently long seismic profiles, a contour map of the Mohorovičić discontinuity for the conterminous United States is compiled. Differences from earlier interpretations are discussed....
