Water levels in artesian and nonartesian aquifers of Florida, 1977-78
Henry G. Healy
1980, Open-File Report 80-693
During 1977 and 1978, water levels in the Floridan aquifer throughout most of north and central peninsular Florida rose 1 to 3 feet, based on water levels measured in 380 wells selected from a network of about 5,000 observation wells for which measurements are in the files of the U.S....
Results of hydraulic tests in wells DOE-1, 2, 3, Salt Valley, Grand County, Utah
F. Eugene Rush, I. M. Hart, M.S. Whitfield, T.F. Giles, T. E. D’Epagnier
1980, Open-File Report 80-205
Three exploratory wells were drilled for geological, geophysical, and hydrological purposes in Salt Valley, Grand County, Utah. Cap rock, salt, and interbeds of the Paradox Member of the Hermosa Formation of Middle Pennsylvanian age were penetrated. The observed depth below land surface of the cap rock-salt interface ranges from 163...
Grinnell and Sperry Glaciers, Glacier National Park, Montana: A record of vanishing ice
Arthur Johnson
1980, Professional Paper 1180
Grinnell and Sperry Glaciers, in Glacier National Park, Mont., have both shrunk considerably since their discovery in 1887 and 1895, respectively. This shrinkage, a reflection of climatic conditions, is evident when photographs taken at the time of discovery are compared with later photographs. Annual precipitation and terminus-recession measurements, together with...
Quantitative analysis versus semiquantitative optical emission spectrographic analysis of chromium, nickel, zinc, vanadium, and molybdenum in organic-rich Paleozoic marine strata, Western United States
George A. Desborough, F. G. Poole, Edwin K. Maughan, H.L. Groves, Gregory N. Green
1980, Open-File Report 80-1271
Comparison of analytical results between the quantitative method and the semiquantitative six-step optical-emission spectrographic method commonly shows significantly lower values for the semiquantitative method. The lower values are most obvious for splits from the same samples of fine-grained organic-rich rocks where the concentrations of the metals chromium, nickel, zinc, vanadium,...
Geologic field trip guide for Cenozoic stratigraphy of southwestern Washington
John M. Armentrout
1980, Open-File Report 80-362
This summary of southwestern Washington stratigraphy describes the principal Tertiary formations comprising the Cenozoic sequences. A field trip road log provides directions for access to type and/or reference localities for each formation discussed.Tertiary rocks of southwestern Washington, measuring nearly 13,000 feet in thickness, are mapped as thirteen formational units. These...
