Intermediate-scale vegetation mapping of Innoko National Wildlife Refuge, Alaska using Landsat MSS digital data
Stephen S. Talbot, Carl J. Markon
1988, Photogrammetric Engineering and Remote Sensing (54) 377-383
A Landsat-derived vegetation map was prepared for lnnoko National Wildlife Refuge. The refuge lies within the northern boreal subzone of northwestern central Alaska. Six major vegetation classes and 21 subclasses were recognized: forest (closed needleleaf, open needleleaf, needleleaf woodland, mixed, and broadleaf); broadleaf scrub (lowland, upland burn regeneration, subalpine); dwarf...
NOAA-10 AVHRR thermal-infrared image of the Colorado Rocky Mountains
Kevin P. Gallo, Bruce K. Quirk, Joy J. Hood
1988, Photogrammetric Engineering and Remote Sensing (54) 777
This month we demonstrate an example of the use of thermal infrared imagery to produce a relatively sharp surrogate shaded-relief image. The image shows one aspect of the drama and usefulness of calibrated thermal imagery that (because of compatible projection and pixel size) can be easily combined with other spectral...
Maps for America: cartographic products of the U.S. Geological Survey and others
Morris M. Thompson
1988, Report
"Maps for America" was originally published in 1979 as a Centennial Volume commemorating the Geological Survey's hundred years of service (1879 - 1979) in the earth sciences. It was an eminently fitting Centennial Year publication, for, since its establishment, the Geological Survey has continuously carried on an extensive program of...
Strontium-isotope stratigraphy of Enewetak Atoll
K.R. Ludwig, Robert B. Halley, Kathleen R. Simmons, Zell E. Peterman
1988, Geology (16) 173-177
87Sr/86Sr ratios determined for samples from a 350 m core of Neogene lagoonal, shallow-water limestones from Enewetak Atoll display a remarkably informative trend. Like the recently published data for Deep Sea Drilling Project (DSDP) carbonates, 87Sr/86Sr at Enewetak increases monotonically but not smoothly from...
Climate and ephemeral-stream processes: Twentieth-century geomorphology and alluvial stratigraphy of the Little Colorado River, Arizona
Richard Hereford
1988, GSA Bulletin (95) 654-668
During the first 40 years of the twentieth century, erosion was the dominant geomorphic process affecting the morphology of the Little Colorado River channel. The discharge regimen was one of frequent large floods and high annual discharge that created a wide sandy channel free of vegetation. In the 1940s and...
Relation of pH and other soil variables to concentrations of Pb, Cu, Zn, Cd, and Se in earthworms
W. Nelson Beyer, Gary L. Hensler, Jeff Moore
1987, Pedobiologia (30) 167-172
Various soil treatments (clay, composted peat, superphosphate, sulfur, calcium carbonate, calcium chloride, zinc chloride, selenous acid) were added to experimental field plots to test the effect of different soil variables on the concentrations of 5 elements in earthworms (Pb, Cu, Zn, Cd. SE). Concentrations of the 5 elements were related...

Bibliography of U.S. Geological Survey water-resources reports for Utah
1987, Utah Division of Water Rights Information Bulletin 28
This bibliography contains a complete listing to December 31, 1986, of reports relating to the water resources of Utah prepared by personnel of the U.S. Geological Survey. Discussions of the related subjects of geology, hydrology, and chemical quality of the water are included in many of the reports. The reports...
Base of moderately saline ground water in the Uinta Basin, Utah, with an introductory section describing the methods used in determining its position
Lewis Howells, M.S. Longson, Gilbert L. Hunt
1987, Technical Publication 92
The base of the moderately saline water (water that contains from 3,000 to 10,000 milligrams per liter of dissolved solids) was mapped by using available water-quality data and by determining formation-water resistivities from geophysical well logs based on the resistivity-porosity, spontaneous potential, and resistivity-ratio methods. The contour map developed from...
Seepage studies of the Weber River and the Davis-Weber and Ogden Valley canals Davis and Weber Counties, Utah, 1985
L. R. Herbert, R.W. Cruff, D.W. Clark, Charles Avery
1987, Technical Publication 90
Studies of selected reaches of the Weber River, Davis-Weber Canal, and the Ogden Valley Canal in Davis and Weber Counties, Utah, were made to determine gains or losses of flow in those reaches. Three to five sets of seepage measurements were made on the river and each canal during 1985....
Seepage study of a 15.3-mile section of the central Utah canal, Pahvant Valley, Millard County, Utah
Michael Enright
1987, Technical Publication 91
Three sets of seepage measurements were made at ten canal sites and at all turnouts along a 15.3-mile section of the Central Utah Canal during the summer of 1986. The total loss for the 15.3-mile section averaged about 36 cubic feet per second or 2.4 cubic feet per second per...
Morgan Hill, California Earthquake, April 1984
Henry Spall, editor(s)
1987, Earthquake Information Bulletin (USGS) (17) 173-176
The Morgan Hill earthquake, a moderate-size (Mg=6.1, ML =6.2, M=6.2) event, was felt throughout central California on April 24, 1984. The epicenter of the earthquake was located near Halls Valley southwest of Mount Hamilton, and the event is presumed to have occurred on the Calaveras fault. Damage, however, was...

A detailed chronology of the most recent eruption period at Mount Hood, Oregon
Kenneth A. Cameron, P. T. Pringle
1987, Geological Society of America Bulletin (99) 845-851
The most recent eruptive period of Mount Hood volcano, the Old Maid eruptive period, was characterized by volcano-hydrologic events (hydrologic events initiated by volcanic activity) which resulted in extensive lahar inundation in the White, Sandy, and Zigzag River drainages and produced a lithic pyroclastic flow which traveled at least 9...
