Natural history of the King Rail
Brooke Meanley
1969, North American Fauna 67
The King Rail (Rallus elegans Audubon), largest of North American rails, is indeed an elegant bird, as its Latin name implies. Its striking appearance (fig. I), secretive nature, and association with a variety of wetland habitats make it a favorite of bird students and rail hunters. The King Rail is...
Foraminiferal zonation and carbonate facies of the Mississippian and Pennsylvanian Lisburne Group, central and eastern Brooks Range, Arctic Alaska
Augustus K. Armstrong, Bernard L. Mamet, J. Thomas Dutro Jr.
1969, Open-File Report 69-14
The Lisburne Group carbonates of the central and eastern Brooks Range contain foraminiferal assemblages assigned to zones of Osage [late Tournaisian], Early Mississippian, to Atoka [early Moscovian], Middle Pennsylvanian age. Representatives of both Eurasiatic and American cratonic microfaunas permit correlation with the original Carboniferous type sections in western Europe as...
Weighted triangulation adjustment
Walter L. Anderson
1969, Open-File Report 69-10
The variation of coordinates method is employed to perform a weighted least squares adjustment of horizontal survey networks. Geodetic coordinates are required for each fixed and adjustable station. A preliminary inverse geodetic position computation is made for each observed line. Weights associated with each observed equation for direction, azimuth, and...
Ground-water levels in observation wells in Oklahoma, 1967-68
R.H. Bingham
1969, Open-File Report 69-335
The investigation of the ground-water resources of Oklahoma by the U.S. Geological Survey in cooperation with the Oklahoma Water Resources Board includes a continuing program to collect records of water levels in selected observation wells on a systematic basis. These water-level records: (1) provide an index to available ground-water supplies;...
Preliminary carbonate lithofacies maps and possible dolomite porosity trends, Mississippian-Pennsylvanian Lisburne Group, North Slope, Alaska
Augustus K. Armstrong
1969, Open-File Report 69-13
Carbonate porosity within the Mississippian-Pennsylvanian age Lisburne Group is probably extensively developed in the subsurface of the North Slope. The Lisburne Group may prove to be one of the more significant reservoir zones in the region and should not be overlooked in any exploration program. Isopach maps for the total...
Water levels and artesian pressures in the Chad Basin of northeastern Nigeria, 1963-68
S.W. Carmalt, G. Chase Tibbitts Jr.
1969, Open-File Report 72-61
This report presents records of water levels and artesian pressures collected during 1963-68 on an observational network of 116 dug wells and boreholes (drilled wells) in the Chad Basin of northeastern Nigeria. The Chad Basin is underlain by the Chad Formation, a series of fluvio-lacustrine sediments which attain a thickness...
