Toward a Federal Land Information System: Experiences and issues
James A. Sturdevant
1988, Bulletin 1852
From 1983 to 1987, the U.S. Geological Survey conducted research to develop a national resource data base of Federal lands under the auspices of the Federal Land Information System (FLIS) program. The program's goal was to develop the capability to provide information to national mineral-use policymakers. Prototype spatial data bases...

Sherman P. Marsh, Gary L. Raines, Michael F. Diggles, Keith A. Howard, Robert W. Simpson, Donald B. Hoover, James Ridenour, Phillip R. Moyle, Spencee L. Willett
1988, Bulletin 1713-D
At the request of the U.S. Bureau of Land Management, approximately 85,100 acres of the Whipple Mountains Wilderness Study Area (CDCA-312) and 1,380 acres of the Whipple Mountains Addition Wilderness Study Area (AZ-050-010) were evaluated for identified mineral resources (known) and mineral resource potential (undiscovered). In this report, the Whipple...
Landslides triggered by earthquakes in the central Mississippi Valley, Tennessee and Kentucky
Randall W. Jibson, David K. Keefer
1988, Professional Paper 1336-C
We mapped 221 large (more than 200 ft across) landslides of three morphologically distinct types on the bluffs bordering the Mississippi alluvial plain in western Tennessee and Kentucky Old coherent slides (146 landslides, or 66 percent of the total) include translational block slides and single and multiple-block rotational slumps, all...
Summary of the hydrology of the Floridan aquifer system in Florida and in parts of Georgia, South Carolina, and Alabama
Richard H. Johnston, Peter W. Bush
1988, Professional Paper 1403-A
The Floridan aquifer system is one of the major sources of ground-water supplies in the United States. This highly productive aquifer system underlies all of Florida, southern Georgia, and small parts of adjoining Alabama and South Carolina, for a total area of about 100,000 square miles. About 3 billion gallons...
Geology and resources of thorium and associated elements in the Wet Mountains area, Fremont and Custer counties, Colorado
T.J. Armbrustmacher
1988, Professional Paper 1049-F
Thorium in potentially economic amounts occurs in three types of deposits in the Wet Mountains area of Colorado: (1) quartz-baritethorite veins and fracture zones, (2) carbonatite dikes, and (3) red syenite dikes. The quartz-barite-thorite veins and fracture zones contain the largest resources of thorium; they cut all Precambrian and Paleozoic...
Benthic macrofauna and ancillary data for San Francisco Bay, California, March to November 1987
Laurence E. Schemel, Allan Y. Ota, J.G. Harmon, J. M. Shay, R.N. Adorado
1988, Open-File Report 88-192
Benthic macrofauna and ancillary data were collected during 1987 as part of the U.S. Geological Survey Regional Effects Monitoring Program in San Francisco Bay, California. Data were collected during five cruises at 2-month intervals from March through November. Benthic macrofauna for identification of species and sediment for size analysis were...
