A Proposed Method For Classifying And Evaluating Soils On The Basis Of Productivity And Use Suitabilities, Arthur Anderson, A. P. Nelson, F. A. Hayes, I. D. Wood
A Proposed Method For Classifying And Evaluating Soils On The Basis Of Productivity And Use Suitabilities, Arthur Anderson, A. P. Nelson, F. A. Hayes, I. D. Wood
Nebraska Agricultural Experiment Station: Historical Research Bulletins
It is the object of this paper to present a method for classifying and evaluating the soils as mapped in regular soil surveys on the basis of land types, which are here defined as areas having reasonably similar productivity and use suitabilities. The standards used to differentiate land types will vary according to the desired objectives, but any material difference in yield, or in practices necessary to maintain a desirable level of productivity will justify recognition of land types. The proposed procedure involves a more detailed study of the influence which soils, slope, erosion, and drainage have on specific crops …

The Geology Of The Southern Central Portion Of The Morrison Cave Area., Arthur Talpt
Bachelors Theses and Reports, 1928 - 1970
Morrison Cave is located about 50 miles southeast of Butte, Montana. It was named after the man who discovered it. Later it was taken over by the State and renamed Morrison Cave State Park. Recently the government with the aid of the Civilian Conservation Corps has built a new road to the cave and has made the interior more accessible. The name of the cave is now Lewis and Clark Cavern National Monument.
A Mechanical Analysis Of The Oriskany Sandstone In Northwestern Virginia, Selma G. Hirsh
A Mechanical Analysis Of The Oriskany Sandstone In Northwestern Virginia, Selma G. Hirsh
Honors Papers
The primary purpose of this paper is to present specific data as a means of explaining the sedimentation conditions at the time of deposition of the Oriskany Sandstone. The data were obtained through the use of laboratory methods upon specimens taken from several outcrops in the vicinity of Monterey, Virginia (see Darton's U.S.G.S. folio No. 51). In addition to the presentation of objective results, the author has attempted to make tentative interpretations of them, based primarily upon textural and shape analysis of the sediment. The writer realizes that the investigation is inadequate in many respects, due to lack of time …

The Paleozoic Stratigraphy Of Lorain County, Ohio, Edwin Hugo Wenberg
The Paleozoic Stratigraphy Of Lorain County, Ohio, Edwin Hugo Wenberg
Honors Papers
During the course of the school year 1936-37 spent at Oberlin, which is situated near the center of Lorain County, Ohio, the writer had the opportunity to study the outcrops and to gather records of wells in this area.
A study of the strata of this county is confusing because the same rocks have been described under different formational names. Originally many of these strata were traced northward from type sections in central Ohio or westward from type sections near Cleveland. At a later date many of the strata were reclassified and assigned to formations which had been traced westward …

Oil And Gas Resources, Jackson County, Missouri, Joseph Robinson Clair
Masters Theses
"The oil and gas production in Jackson County, though rather small, is nevertheless of considerable economic importance. A portion of the county has been rather thoroughly developed but the remainder has had little prospecting. In order to aid further development in the region the Missouri Geological Survey engaged in the mapping of all the known wells in the county as a basis for preparing a structural contour map of the area. In addition, a member of the Survey staff is stationed permanently in Kansas City to give assistance to the operators in the region and to collect the logs of …

Geology And Ground-Water Resources Of South-Central Nebraska. With Special Reference To The Platte River Valley Between Chapman And Gothenburg, Alvin Leonard Lugn, L. K. Wenzel
Department of Earth and Atmospheric Sciences: Faculty Publications
The investigation here reported, which covered a period of about 5 years, 1929 to 1933, was made for the purpose of determining the available supply of ground water in south-central Nebraska, the origin and discharge of the ground water, and the relation of the geologic and ground-water conditions in the Platte River Valley to the conditions occurring under the plains to the south. The area was found to be underlain by permeable Pleistocene and Tertiary sand .and gravel, much of which is saturated and yields relatively large quantities of water to wells. Except in a few isolated places the ground-water …

Remarkable West American Fossil, The Blue Lake Rhino, George F. Beck
Remarkable West American Fossil, The Blue Lake Rhino, George F. Beck
All Faculty Scholarship for the College of the Sciences
Bidding for acceptance as fact, and for its place in the sun of fame and notoriety, we come now to the newly discovered fossil rhino animal mold of Blue Lake in Grand Coulee, central Washington. Not that fossil rhinos are rare or that their abundance in the Tertiary of America has waited until the present for revelation, is this fossil important. The feature in the Blue Lake rhino which taxes our credulity is the existence of the thing in what unquestionably must pass as once liquid basaltic lava. That anything organic could pass through the terrific heat and pressure of …
