The Mustinka and Bois de Sioux Rivers watershed is mantled by till deposits with scattered sand deposits. The west-central and northwestern part of the watershed was covered by Glacial Lake Agassiz and the resulting land surface is a flat, lake-washed till plain. Patches and ridges of sand scattered throughout the lake...
Sedimentary features of the Blackhawk formation (Cretaceous) at Sunnyside, Carbon County, Utah
John O. Maberry
1968, Open-File Report 68-170
The Blackhawk Formation at Sunnyside, Utah, was deposited along the western margin of the Western Interior Cretaceous sea during southeastward withdrawal of the sea. Sand was the dominant type of land-derived sediment deposited in the Sunnyside district during the regressive phases. Sand bodies prograded seaward in response to changing sediment...

Puerto Rico, the closest land area, has a central longitudinal core of Cretaceous and early Tertiary volcanic rocks, some serpentinite of undetermined age, and numerous small...
Effect of predator reduction on waterfowl nesting success
D. S. Balser, Herbert H. Dill, H.K. Nelson
1968, Journal of Wildlife Management (32) 669-682
A 6-year study to determine the effect of nest-predator removal on waterfowl nesting success was conducted at the Agassiz National Wildlife Refuge in northwestern Minnesota from 1959 through 1964. Predators were removed from the west side of the Refuge while the east side served as a control area. At the...
Hornblendes from granitic rocks of the central Sierra Nevada batholith, California

1968, Journal of Petrology (9) 378-410
Twenty samples of hornblendes from rocks of 14 plutonic units in the central Sierra Nevada and Inyo Mountains, California, have been studied in detail. Optical, density, single-crystal and powder X-ray diffraction, and major and minor element chemical data are reported.The compositions of the hornblendes show only limited correlation with the...

1968, Journal of Geophysical Research (73) 3989-4043
A total of 6315 pictures were taken by the television camera on Surveyor 3 after the lunar landing. These pictures have provided much new information about the location of the landing site on the moon, the detailed topographic and geologic characteristics of the lunar surface, and the appearance of the...
Tectonic emplacement of the Burro Mountain ultramafic body, Santa Lucia Range, California
Stephen H. Burch
1968, GSA Bulletin (79) 527-544
The Burro Mountain body is a crudely equidimensional block of unusually fresh ultramafic rock. This block, along with numerous smaller and more elongate serpentinite bodies, has been emplaced in a highly sheared Franciscan terrane immediately west of the Nacimiento fault. This fault separates two major structural units: (1) on the...
New theory of recharge to the artesian basin of the Dakotas
F. A. Swenson
1968, Geological Society of America Bulletin (79) 163-182
The artesian basin of the Dakotas has been studied for many years. The widely held concept has been that recharge enters the equivalents of the Dakota Sandstone, where they are exposed on the flanks of the Black Hills, and moves through this formation to the area of maximum development of the aquifer in eastern North Dakota and South Dakota. Some anomalies, difficult...

Overlapping plutonism, volcanism, and tectonism in the boulder batholith region, western Montana
G.D. Robinson, M. R. Klepper, J. D. Obradovich
1968, Memoir of the Geological Society of America (116) 557-576
It is well known that the Boulder batholith region experienced intensive plutonism, volcanism, and tectonism that all began in Late Cretaceous time, after at least 700 m.y. of structural and igneous inactivity except for sporadic epeirogeny. Recent stratigraphic, structural, paleontologic, arid, especially, radiometric evidence makes it possible to date these...

Movements of adult lake trout in Lake Superior
Jerold F. Rahrer
1968, Transactions of the American Fisheries Society (97) 481-484
Returns from mature lake trout (Salvelinus namaycush) tagged in western Lake Superior in 1959 and 1962-65 described here suggest that trout disperse widely from the spawning grounds after spawning and return in subsequent years. Although the data were not extensive, returns from lake trout tagged near Keweenaw Point in 1950...
