“…Soil association units were derived from soil association maps of Texas (Godfrey et al, 1973), New Mexico (Soil Survey Staff, USDA-SCS, 1974) and the Great Plains (Aandahl, 1972). Some small associations were combined with adjacent larger units for the New Mexico portion, and the Brownfield-Tivoli Taxajunct was extended into West Texas.…”

Blowing dust is a common phenomenon at Lubbock, Texas, on the Southern High Plains. The directional variability of blowing dust estimated with the 'sand rose' technique, using wind speed and direction data, suggest that dust transport occurs from all directions. An empirical method of determining directional variability using meteorological data on visibility reductions due to blowing dust, however, indicates that most dust comes from the west and south-west. In addition to wind speed and direction, other environmental factors must be considered in explaining the spatial pattern of dust transport. Soil erodibility is variable in the region, with the most extensive area of highly erodible soils to the west and south-west of Lubbock. Rangeland dominates land use to the east, while agriculture is extensive to the north, west and south. Local farming techniques leave bare soil during the winter and spring, when most airborne dust is produced and also when strong winds are common from the west and south-west. Soil moisture is lowest to the southwest of Lubbock, which leads to a decrease in soil structure and an increase in the potential for wind erosion in that direction. Relative humidities affect threshold wind speeds and are lowest during March and April, when winds are common from the west and south-west. The spatial and seasonal variability and interactions between many factors, both natural and human-controlled, must therefore considered in explaining the directional variability of aeolian sediment transport at Lubbock.

“…This means that carbonate leaching preceded clay translocation, a typical case of soil Btk horizon formation (Buol, 1989). The presence of carbonate-marked (not filled) plant root canals and clay lenses of varying sizes in the carbonate-enriched zones supports the argument that the carbonate-enriched zones were formed pedogenically (Aandahl, 1982;Gile et al, 1966;Machatte, 1985;Reheis, 1987). The fact that each platy carbonate horizon overlies a plugged carbonate horizon consisting of loose carbonate nodules or cylinders within each of the carbonate-enriched zones also suggests pedogenic formation (Gile et al, 1966;West et al, 1988).…”

“…The carbonate of the Holocene soil and loess are not in comparison with the 6I8O peak of stage 1 in the Pacific core. The concentration of pedogenic carbonate is, in general, inversely related to the effective soil moisture in semiarid-subhumid environments (Aandahl, 1982;Ruhe, 1970). Possible explanations for the low concentration of carbonate in the Holocene soil relative to the carbonate-enriched zones within the Loveland Loess include: (1) the soil effective moisture might have been higher in the Holocene; (2) the soil-forming duration might have been shorter in the Holocene; (3) the dust influx might have been higher in the Holocene.…”

Based on interpolation of thermoluminescence dates and the mean accumulation rate of 0.034 mm yr-' , four cycles of pedogenic CaC03 accumulation are found within the Loveland Loess: 41 5-325 ka, 325-250 ka, 250-195 ka and 195-95 ka. The four CaC03 peaks correspond chronologically to marine oxygen isotope stages 11, 9, 7 and 5, respectively. The early Wisconsin (95-70 ka) was characterized by sand dune activity. The reddish pedocomplex was formed from 70 to 35ka under relatively warm and moist climatic conditions with a very slow rate of silt accumulation (0.016 mm yr-'). The Gilman Canyon pedocomplex, enriched in organic matter and dated at 35-20 ka, was formed under a strong physical weathering regime and a relatively high rate of silt accumulation (0.15mmyr-'), indicating a windy, relatively moist, probably cool environment. It developed when the Laurentide ice sheet was advancing and dust content in Greenland ice core was low. The Peoria Loess was accumulated at a rate of 0.3 mm yr-I in central Kansas under cold dry conditions when the ice sheet fluctuated around its maximum position and the dust content in the Greenland ice core was the highest. Even the warm substage around 13 ka has some corresponding evidence in the central Great Plains. The welldeveloped Brady Soil, dated at 10.5-8.5 ka, indicates that the early Holocene was the optimal time for soil development since 20 ka. The poorly weathered Bignell Loess might have been deposited during the Altithermal Period from 8.5 to 6 ka.

A Cultural Resource Inventory of the Left Bank of Lake Oahe: Burleigh and Emmons Counties, North Dakota. Volume 1

An intensive cultural resource inventory was conducted on approximately 8200 acres of federal land adjacent to Lake Oahe in Emmons and Burleigh counties, North Dakota. Seventy-two sites and 23 isolated finds were recorded. Seven sites are believed eligible for nomination to the National Register of Historic Places. Further work is necessary to determine eligibility at 29 sites. Preliminary site patterning studies indicate that the modeling of site location is possible with a high degree of accuracy. It is believed that such modeling would be of use for long-term and short-term management and research concerns.
