Chemical input-output analyses were used to evaluate the rate of rock weathering and soil development on a granitic inselberg of the Dragoon Mountains in southeastern Arizona. Soil genesis relationships were investigated through field and laboratory study of the soil profile, parent rock, microclimate and vegetation, on different catena positions and hillside aspects. Precipitation and runoff water qualities were determined, with increased summer acidity. Precipitation volume was estimated by extrapolating data from a nearby recording station. Runoff volume was estimated by the U.S.D.A.-S.C.S. Curve Number Method (1972). These data enabled the quantitative determination of cationic solution loss. The indicated decreasing order of cation mobility is calcium, sodium, potassium and magnesium. Cations of higher mobility are relatively depleted in the hillcrest soils, while transported to the footslope or beyond. Calcium, and to a lesser extent sodium, have experienced more extensive off-site removal. Differences resulting from the transformation of parent material to soil were analyzed by field morphology, X-ray analysis, laser light-scattering particle size analysis, and chemical analyses. The study site was surveyed, mapped and the spatial arrangement of soil taxa and their compositional variation were studied. Nearly all pedons on the crest or transport slope are Lithic Ustic Torriorthents; whereas footslope soils show greater development, as exemplified by the occurrence of various Haplargids, Haplustolls and Argiustolls. Weathering rates were calculated using a methodology similar to that of F. W. Barth (1961). Potassium and magnesium provided the most reasonable data of 350 and 430 Kg ha⁻¹ yr⁻¹, respectively. (equivalent to 13.5 and 16.5 mm of rock weathered per 1000 years). Two serrated projectile points were found inbedded on the clayey soil surface of an adjacent ancient pond site. These artifacts resemble another projectile point found in southeastern Arizona which has been radiocarbon dated ~7,000 yr B.P. A minimum age for the pond and immediate surrounding topography is suggested to correspond with the end of the western subhumid pluvial period. The assessment of the geochemical budget provided a valuable framework for quantification of the various processes which interactively determine the rates of weathering and soil formation.

abstract: During the 1850s, Indian policy objectives pursued by the civil and military branches of government in New Mexico would have a lasting impact on future relations between the two cultures. Many later policies originated in this antebellum period, but often receive only a summary analysis by scholars who focus on the more popular post-Civil War period. Debates over proper policies and enforcement would proliferate in the 1850s as military and civil officials vied with one another over their own perceived authority. Many officials pursued viable policies, but did not remain in office long enough to ensure their implementation. Additionally, personal egos and stubbornness often undermined interagency cooperation. An overall cultural misunderstanding regarding Apache tribal structure and the inability to distinguish between subgroups exacerbated the conflict. Anti-Indian sentiments prevailed in the military, which often contradicted the more humanitarian approach advocated by the Indian Department. As a result, a contention for power and prestige emerged on three separate fronts: civil government leaders, military leaders, and within the Apache tribe. This thesis offers a contextualization of events that transpired during the 1870s and 1880s by demonstrating how these three entities contended amongst each other for power, undermining policy objectives in the antebellum era. Americans sought to conquer and control--to exert authority and power--over all components of the western landscape in order that they might realize its full economic potential. The Apaches formed a part of this landscape much the same as lofty mountain ranges, raging rivers, and parched deserts. All of these required conquering before that nineteenth century American dream could be fully imbued in the Southwest, and over the several decades following Kearny's arrival countless individuals streamed westward in torrents intent on accomplishing just that. The Apaches, like all western tribes, thus fell into an unstoppable cycle of conquest driven by an insatiable Anglo-American obsession with exerting control. Just as swarthy lawyers challenged claims to gain legal dominion over western tracts of land; just as engineers constructed dams and sought ways to manipulate streams and rivers; just as the plow tilled millions of acres of raw lands; just as the miner's pick slowly chipped away at formidable peaks; so too did the United States Army subdue the Apaches, all of these being a means towards a common end for the American West. / Dissertation/Thesis / M.A. History 2011

In August, 1944, the Allies embarked on one of the "two supreme operations of 1944," Operation Anvil/Dragoon. It is an operation that almost did not happen. Envisioned as a direct supporting operation of Overlord, Anvil soon ran into troubles. Other operations taking away resources away from Anvil in addition to opposition from the highest levels of Allied command threatened Anvil. This thesis chronicles the evolution of this debate, as well as shed light on one of the most overlooked and successful operations the Allies embarked on in World War II.

This thesis deals with the life and career and intimate life of Francis Carroll Grevemberg, an antiaircraft World War II officer from New Orleans, Louisiana. Grevemberg joined the Louisiana National Guard in 1932 and began his military career in the midst of the Great Depression. In the reorganization of the U.S. Army before World War II, the War Department transformed Grevemberg's cavalry regiment into a coastal artillery battalion with antiaircraft capability. During World War II, Grevemberg saw continuous action in the North Africa, Italy and Southern France. He regularly wrote letters from battlefields to his wife Dorothy. These letters provide a important window into a young officer's feelings, thoughts and affection in the unfolding of World War II. They are documents of a soldier's emotional release during times of crises. Lt. Col. Grevemberg is a rare, World War II antiaircraft artillery officer who took part and survived five amphibious landings in the Mediterranean.
