Regional Implications Of The Geology Of The Ogallala Group (Upper Tertiary) Of Southwestern Morrill County, Nebraska, And Adjacent Areas, Robert F. Diffendal Jr.
Regional Implications Of The Geology Of The Ogallala Group (Upper Tertiary) Of Southwestern Morrill County, Nebraska, And Adjacent Areas, Robert F. Diffendal Jr.
Robert F. Diffendal, Jr., Publications
A part of a filled Ogallala Group (upper Tertiary) paleovalley system exhumed by recent stream erosion in southwestern Morrill County, Nebraska, and adjacent areas contains steep gradient gullies filled with locally derived sediments. Younger channels filled with granitic gravels derived by stream erosion of the Rocky Mountains to the west and southwest cut across and through these older filled gullies, indicating that there were at least two periods of downcutting followed by periods of filling during the development of this system.
Individual clasts from younger Ogallala gravels are often as large as or larger than clasts from Quaternary gravels transported …

Reconnaissance Of The Bedrock Aquifers And Groundwater Chemistry Of Crawford, Franklin, And Sebastian Counties, Arkansas, Samuel R. Rothermel, Wyndal M. Robison, Julie L. Wanslow, James R. Musgrove, Daryll Saulsberry, Albert E. Ogden
Journal of the Arkansas Academy of Science
A ground water reconnaissance of Crawford, Franklin, and Sebastian counties was performed utilizing 122 wells having drillers' logs from bedrock aquifers. North of the Arkansas River, essentially all bedrock wells produce from the Atoka Formation. There are many low producing aquifers within the Atoka with a range in yield of 0.1 to 55 gpm, but having a median yield of only 2 gpm. Well depths range from 18 to 248 feet with a median of 122 feet. More water is generally obtained from the shale/siltstone aquifers than the sandstones due to more bedding-plane partings and more closely spaced fractures. Greater …
Preliminary Investigation Of Ground-Water Occurrence In The Atoka Formation Of Pope And Faulkner Counties, Arkansas, Wyndal M. Goodman, Albert E. Ogden
Preliminary Investigation Of Ground-Water Occurrence In The Atoka Formation Of Pope And Faulkner Counties, Arkansas, Wyndal M. Goodman, Albert E. Ogden
Journal of the Arkansas Academy of Science
One hundred and twelve wells having drillers' logs were studied in Pope and Faulkner counties. Sixty-six of the wells produced water from shales and siltstones of the Atoka Formation while 46 produced from interbedded Atoka sandstones. Drillers' estimated well yields ranged from 1 to 100 gpm, but the median yield was only 9 gpm. Well depths ranged from 30 to 337 feet with a median depth of 100 feet. Ground-water is usually obtained from a series of low-producing confined aquifers of low artesian pressure. Pressure head and production were shown, statistically (a = .01), to decrease with increasing well depth. …

Hydrology Of The Sinking Creek System, Logan And Simpson Counties, Kentucky, James C. Cubbage
Hydrology Of The Sinking Creek System, Logan And Simpson Counties, Kentucky, James C. Cubbage
Masters Theses & Specialist Projects
Southwest of Bowling Green, Kentucky, is the Western Pennyroyal, is a karstified area which has been neglected in the study of its ground water. About 100 square miles near Adairville were chosen for analysis to help rectify this lack of knowledge. The area is dominated by Sinking Creek, a surface-subsurface drainage system.
The main purpose of the study was to map the underground flow in the Sinking Creek area. The drainage system seemed to be typical for the Western Pennyroyal and exhibited many similarities to flow paths known in the Central Kentucky Karst.
The investigation proved to be of basic …

The information pertains to the geology, structure, tectonics, and seismicity of eastern Nebraska with emphasis on central Otoe County. Some of the information presented here results from a combination of studies begun in earlier years but the greater part results from studies begun during the contract year.
The scope of the studies is summarized as follows:

Geology And Groundwater Supplies Of Southern Dawes And Northern Sheridan Counties, Nebraska, Vernon L. Souders
Conservation and Survey Division: Faculty and Staff Publications
The upland plain in southern Dawes and northern Sheridan counties of northwest Nebraska is underlain by rocks of Tertiary age. These rocks overlie those of Cretaceous and Jurassic ages in this region of about 2250 square miles . Strata of Tertiary age are a source of groundwater for most of the irrigation, municipal, stock, and rural-domestic needs of the area.
Nine stratigraphic units of Tertiary.age were defined by examination of test hole samples and logs and by examining electric logs of oil and gas tests, driller's logs of irrigation wells, and outcrops. Stratigraphic correlations are difficult in the area because …

Quaternary Geology Of Chaco Canyon, Northwestern New Mexico, David Waxham Love
Quaternary Geology Of Chaco Canyon, Northwestern New Mexico, David Waxham Love
Earth and Planetary Sciences ETDs
The overall purpose of studying the Quaternary geology of Chaco Canyon is to develop an understanding of how the geomorphic system in the Chaco drainage evolved and how it presently operates. This dissertation has several subsidiary purposes; (1) to describe and relate modern sedimentary features and facies (which are likely to be preserved in the alluvial fill of the canyon) to modern geomorphic processes, (2) to use the results from the study of modern sediments to interpret exposures of alluvium in Chaco Canyon in order to reconstruct past environments, (3) to develop conceptual models of the geologic subsystems of the …

Ash Hollow Historical Park, Robert F. Diffendal Jr.
Robert F. Diffendal, Jr., Publications
Ash Hollow Creek is an intermittent stream forming a southern tributary to the North Platte River. The creek flows only in response to precipitation from locally heavy thunderstorms or to heavy runoff from melting snow in the spring. Western Nebraska has a semi-arid climate and receives less than 20 inches of rainfall per year. Vegetation in the park and surrounding area is typical of the short grass prairie of the Great Plains. Native short grasses grow abundantly on undisturbed tablelands, valley sides, and along principal flood plains of streams and rivers. Prickly pear, barrel cactus, yucca and sagebrush are common …

A Statistical Analysis Of The Quality Of Surface Water In Nebraska, R. A. Engberg
A Statistical Analysis Of The Quality Of Surface Water In Nebraska, R. A. Engberg
United States Geological Survey: Publications
This report provides descriptive statistics for 29 chemical or biological constituents for 109 stream sites in Nebraska sampled by the U.S. Geological Survey beginning in 1946. Also provided for each site are regression equations relating specific conductance to each of 12 chemical constituents and a regression equation relating specific conductance to stream discharge. The descriptive statistics are presented by river basins. Water leaving these basins that has the lowest mean specific conductance (266 umho/cm) is from the Niobrara River at Verdel, and water that has the highest (1,890 umho/cm) is from the South Platte River at Roscoe. Statewide, the principal …
