Potential Geologic Hazards Near The Thistle Landslide, Utah County, Utah, United States Geological Survey
Potential Geologic Hazards Near The Thistle Landslide, Utah County, Utah, United States Geological Survey
All U.S. Government Documents (Utah Regional Depository)
In mid-April, 1983, an old landslide near Thistle, Utah, began to move, and within days had blocked Spanish Fork Canyon. As the slide's movement continued, construction crews gradually converted the toe of the slide into an earth-filled dam--Thistle dam--that impounded northwest-flowing Spanish Fork River. The resultant reservoir, known as Thistle Lake, was subsequently drained because of uncertainty about the stability of the dam. Recently, officials of Utah County have explored various alternatives for a water-retention structure in the area, including utilization of Thistle dam. The Thistle Slide Committee, established by the State of Utah to evaluate the suitability of using …

During 1979-84, 35 wells completed in the principal aquifer in the Salt Lake Valley, Utah, that had been sampled during 1962-67 were resampled to determine if water-quality changes had occurred. The dissolved-solids concentration of the water from 13 of the wells has increased by more than 10 percent since 1962-67.
The Influence Of Viewing Angle On Elk Hiding Cover In Young Timber Stands, United States Department Of Agriculture, Forest Service
The Influence Of Viewing Angle On Elk Hiding Cover In Young Timber Stands, United States Department Of Agriculture, Forest Service
Forestry
Young timber stands, even when providing 100 percent visual concealment for elk when viewed on a horizontal plane, may provide 50 percent or less cover when viewed from an opposing slope at an elevated viewing angle. The higher the viewing angle, the greater the relative cover loss. In a simple linear model, viewing angle explained 52 percent of the variation in hiding cover values. Slightly more variation was accounted for when the data were stratified by tree height. On the average, for a 10-degree elevation in viewing angle, hiding cover decreased by 10 percent. The cover loss relationship was most …

'Hobble Creek' - A Superior Selection Of Low-Elevation Mountain Big Sagebrush, United States Department Of Agriculture, Forest Service
Forestry
This is the foundation document for the release of the 'Hobble Creek' selection of big sagebrush. It is a low-elevation mountain big sagebrush (Artemisia tridentata ssp. vaseyana). 'Hobble Creek' is needed to increase the nutrient content of winter diets of mule deer (Odocoileus hemionus hemionus) and domestic sheep (Ovis aries). This sagebrush exceeds the typical winter forage values in amount of energy-producing compounds, crude protein, phosphorus, and carotene. Of the 186 big sagebrush selections tested. 'Hobble Creek' is the most preferred by wintering mule deer and ranks high in preference by wintering domestic sheep. 'Hobble Creek' does not contain substances …

Visitor Attitudes Toward Wilderness Fire Management Policy -- 1971-84, United States Department Of Agriculture, Forest Service
Wildfires
The historical role of naturally occurring fire in shaping the character of many American landscapes has become an accepted ecological principle. Prior to the coming of the Europeans, natural fires had a major influence in producing a variety of vegetational mosaics. Fire suppression policies of the 20th century, however, significantly changed the evolution of many landscapes compared to what would have occurred had natural fires been allowed to continue. Although natural fires can no longer be allowed to burn in many places because of resource values or danger to the public, such fires may be permitted in many wildernesses and …
Modeling Moisture Content Of Fine Dead Wildland Fuels: Input To The Behave Fire Prediction System, United States Department Of Agriculture, Forest Service
Modeling Moisture Content Of Fine Dead Wildland Fuels: Input To The Behave Fire Prediction System, United States Department Of Agriculture, Forest Service
Wildfires
A method for predicting the time-dependent nature of fine fuel moisture is badly needed to support fire behavior prediction systems used in fire management. Of the models available, none met all the requirements of the BEHAVE fire behavior prediction system. The Canadian Fire Fuel Moisture Code (FFMC) came closest to meeting our needs and was selected as a base model. Improvements to the FFMC were concentrated on providing a means of accounting for annual and diurnal variation due to solar heating of woody fuels. This was necessary because the FFMC was developed for fuels located within forest stands, a generally …

Identification And Analysis Of Climatic Fields Through Dot-Density Shading, Stephen J. Lavin, Randall S. Cerveny
Identification And Analysis Of Climatic Fields Through Dot-Density Shading, Stephen J. Lavin, Randall S. Cerveny
Department of Earth and Atmospheric Sciences: Faculty Publications
Gridded matrices of climatic data can be mapped by computer with a variety of symbolization methods, all of which have some shortcomings. A new mapping procedure, dot-density shading, is herein proposed as an alternative mapping form. Dot-density shading produces continuous-appearing dot patterns whose density is proportional to the data. Significant algorithms are those for computing dot numerosity and quasi-random dot placement. A number of application including data error detection and anomaly recognition are discussed.

Diatom Stratigraphy Of The Lower Pliocene Part Of The Sisquoc Formation, Harris Grade Section, California, John A. Barron, Jack G. Baldau
United States Geological Survey: Staff Publications
Lower Pliocene diatoms were studied from the Sisquoc Formation and lowermost Foxen Mudstone, exposed along Hams Grade north of Lompoc, California, to refine the diatom biostratigraphy of post-Monterey Formation sediments in California. Sixty-seven diatom taxa were identified in the 25 samples examined from the 790-m thick (2950-ft) section. The diatoms are assignable to the uppermost Nitzschia reinholdii Zone and Thalassiosira oestrupii Zone of Damn (1981), and five tentative subzones for local correlation are proposed. Regional correlations and taxon occurrence are discussed, and the base of the Nitzschia reinholdii Zone is redefined as at the last occurrence of Thalassionema schraderi.

Development Of Oriented Lakes In The Eastern Rainbasin Region Of South Central Nebraska, James P. Krueger
School of Natural Resources: Dissertations, Theses, and Student Research
The Eastern Rainbasin region is located on a relatively flat-lying, loess-covered plain. The gently sloping land surface is poorly drained and in places local drainage is toward basins which lack external drainage. In the spring, excell precipitation collects in these basins, forming small lakes and marshes. It is these ephemeral lakes that give the region its name.

Wheat Growth On Saline Waterlogged Soils, E G. Barrett-Lennard
Wheat Growth On Saline Waterlogged Soils, E G. Barrett-Lennard
Journal of the Department of Agriculture, Western Australia, Series 4
Studies of the growth of plants on salt-affected soils have focused maily on the effects of salt. However, many salt-affected soils are also subject to waterlogging. Glasshouse experiments conducted by the Department of Agriculture have shown that although wheat growth is not greatly reduced by low levels of salt under well drained conditions, under waterlogged conditions such levels of salt can have a severe effect.

Serradella Prospects At Esperance, Michael D A Bolland
Serradella Prospects At Esperance, Michael D A Bolland
Journal of the Department of Agriculture, Western Australia, Series 4
Yellow serradells is a promising introduced annual legume suitable for some of Western Australia's well drained sandy acid soils where other pasture legumes failto persist.
In the Esperance area serradella grows siccessfully on some sandy soils more than 0.5 metres deep. I develops deep roots rapidly - up to three times deeper than subterranean clover - and this is probably the main reason for its persistance.
At present only two late maturing, registered serradella cultivars are available to farmers in southern Australia. This article describes research at Esperance to delect earlier flowering cultivars for persistence in areas with less than …

Rock Phosphates : Fertilisers For Sandy Soils?, J S. Yeates, D. M. Deeley, G. T.B. Cockerton, M. F. Clarke
Journal of the Department of Agriculture, Western Australia, Series 4
Rock phosphates, from which water solubls phosphorus fertilisers such as superphosphate are manufactured, sometimes appear attractive to farmers because of their relatively low cost. But redearch has shown t6hat on most western australian soils they are not economical fertilisers. However, some deep sandy soils of the State's high rainfall area are exeptions. On these soils, rock phosphates compare favourably with superphosphate for plant growth. But how can these deep sands be identified.
This article describes research to define the soil characteristics necessary for rock phosphates and fertilisers containing rock phosphate, such as Coastal superphosphate, to be effective substitutes for superphosphate.
