A model to forecast short-term snowmelt runoff using synoptic observations of streamflow, temperature, and precipitation
Wendell V. Tangborn
1980, Water Resources Research (16) 778-786
Snowmelt runoff is forecast with a statistical model that utilizes daily values of stream discharge, gaged precipitation, and maximum and minimum observations of air temperature. Synoptic observations of these variables are made at existing low- and medium-altitude weather stations, thus eliminating the difficulties and expense of new, high-altitude installations. Four...

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,...

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...
Development of sea lamprey (Petromyzon marinus) larvicides
John H. Howell, John J. Lech, John L. Allen
1980, Canadian Journal of Fisheries and Aquatic Sciences (37) 2103-2107
Larvicides are used to control sea lamprey (Petromyzon marinus) in the Great Lakes. These larvicides are useful because they are more toxic to sea lamprey than fish species found in the same habitat. The lampricides come from two classes of chemical compounds: (1) halonitrophenols, and (2) halonitrosalicylanilides. Selectivity of the...
Thickness change involved in the peat-to- coal transformation for a bituminous coal of Cretaceous age in central Utah
Thomas A. Ryer, A.W. Langer
1980, Journal of Sedimentary Petrology (50) 987-992
The ratio of the thicknesses of a layer of peat and the coal bed formed from that peat has been calculated for a bituminous coal bed in central Utah. The method used involves comparison of the thickness of peat eroded by a laterally...

P.A. Gilderhus, B. G. H. Johnson
1980, Canadian Journal of Fisheries and Aquatic Sciences (37) 1895-1905
The chemicals 3-trifluoromethyl-4-nitrophenol (TFM) or a combination of TFM and 2a??,5-dichloro-4a??-nitrosalicylanilide (Bayer 73) have been used to control the sea lamprey (Petromyzon marinus) in the Great Lakes for about 20 yr. These chemicals cause some mortalities of Oligochaeta and Hirudinea, immature forms of Ephemeroptera (Hexagenia sp.), and certain Trichoptera, Simuliidae,...
About forty last-glacial Lake Missoula jokulhlaups through southern Washington
R. B. Waitt Jr.
1980, Journal of Geology (88) 653-679
The rhythmic Touchet Beds in the Walla Walla and lower Yakima valleys resulted from many separate backfloodings by hydraulically ponded glacial Lake Missoula water. At least once this episodic lake briefly contained half the of water that catastrophically drained the largest glacial Lakes Missoula. Evidence that the...
Impact of horse traffic on trails in Rocky Mountain National Park.
R.M. Summer
1980, Journal of Soil and Water Conservation (35) 85-87
Disturbances related to the impact of horses on trails in Rocky Mountain National Park vary across the landscape. Geomorphic monitoring of permanent sites suggests that horse traffic is not the single, dominant process active on trails, nor is degredation always a direct result of horse use. Instead, amounts and rates...
