The earthquake educational institute at San Francisco State University
R. Sullivan, R. Pestrong, H. Strongin
1980, Earthquake Information Bulletin (USGS) (12) 174-176
The Earthquake Educational Institute was established in 1978 at San Francisco State University under a grant from the U.S National Science Foundation. The goal of the Institute is to develop earthquake-related curricula for use in elementary and secondary schools in the hope that, by educating students about earthquakes, they will...
Early concentrations of Brown Pelicans along southern Oregon coast
Charles J. Henny, J.A. Collins
1980, Murrelet (61) 99-100
The California Brown Pelican (Pelecanus occidentalis californicus), which nests in southern California and Mexico, wanders north along the coast after the breeding season, sometimes as far as southern British Columbia (A.O.U. 1957). Anderson and Anderson (1976) and Ainley (1972) report that Mexico-originating pelicans disperse north in late summer and fall,...
Wilderness permit compliance and validity
J. W. van Wagtendonk, J.M. Benedict
1980, Journal of Forestry (78) 399-401
In Yosemite National Park, 92 percent of the parties using back country areas had permits. Parties without permits were smaller in size and stayed for shorter periods of time. For all parties with permits, 62 percent made changes to their trips. Parties changing their trips in both time and...

Epizootic of coccidiosis in free-flying lesser scaup (Aythya affinis)
R. M. Windingstad, M.E. McDonald, Louis N. Locke, S.M. Kerr, J.A. Sinn
1980, Avian Diseases (24) 1044-1049
A coccidiosis epizootic has occurred in lesser scaup (Aythya affinis) at Bluestem Reservoir in eastern Nebraska during the spring in each of three recent years: 1976-1978. Losses peaked during the period from mid-March through April. As much as 29% of the peak population of scaup using the reservoir died. Necropsies...
Travel time variation on backcountry trails
J. W. van Wagtendonk, J.M. Benedict
1980, Journal of Leisure Research (12) 99-106
Numerous interrelated factors influence the travel times of hikers and riders on backcountry trails. This study sought to quantify those factors which were thought to be most important in affecting trail speeds. The travel times of 897 backpacking parties, 634 day hiking parties, and 111 riding parties were obtained from...

This permanent catalog is a list of books and maps that were published between 1962 and 1970. It supplements another permanent catalog "Publications of the Geological Survey, 1879-1961."...
Estimating earthquake potential
R.A. Page
1980, Earthquake Information Bulletin (USGS) (12) 16-24
The hazards to life and property from earthquakes can be minimized in three ways. First, structures can be designed and built to resist the effects of earthquakes. Second, the location of structures and human activities can be chosen to avoid or to limit the use of areas known to be...
Toxicity of five forest insecticides to cutthroat trout and two species of aquatic invertebrates
D. F. Woodward, W.L. Mauck
1980, Bulletin of Environmental Contamination and Toxicology (25) 846-854
The Northern Rocky Mountain region has had scattered infestation of the western spruce budworm Christoneura occidentalis since the early 1900's (U.S. DEPARTMENT OF AGRICULTURE (USDA) 1976b). On the basis of aerial surveys in 1975, TUNNOCK et al. (1976), estimated that budworm defoliation occurred on 2,278,804 acres of six National Forests...
Biogenic and thermogenic origins of natural gas in Cook Inlet basin, Alaska.
George E. Claypool, C. N. Threlkeld, L. B. Magoon
1980, American Association of Petroleum Geologists Bulletin (64) 1131-1139
Two types of natural gas occurrences are present in the Cook Inlet basin. The major reserves (1.8 × 1011m3) occur in shallow (less than 2,300 m), nonassociated dry gas fields that contain methane with ^dgr13C in the range of -63 to -56 per mil. These gas fields are in sandstones...
Visitor use patterns in Yosemite National Park
J. W. van Wagtendonk
1980, Journal of Travel Research (19) 12-17
After several years of dramatic increases, visitor use in Yosemite National Park has leveled off to an average of 2.4 million visits per year. Coincident with this decline in the growth rate, there have been some changes in visitation trends and patterns. Data collected in the park show that the...
Organic content of Devonian shale in western Appalachian basin
James W. Schmoker
1980, American Association of Petroleum Geologists Bulletin (64) 2156-2165
In the organic-rich facies of the Devonian shale in the western part of the Appalachian basin, the distribution of organic matter provides an indirect measure of both gas in place and the capacity of the shale to supply gas to permeable pathways.The boundary between organic-rich ('black') and organic-poor ('gray') facies...
