This concluding chapter demonstrates that under state management, Starved Rock State Park grew in popularity. The park provided specialists from the US Army Corps of Engineers with a training area to master the military art of pontoon bridge assembly in preparation for the Allied invasion of Germany in World War II. Equally important, the park was where locals came to work and to relax in the 1950s and 1960s, and it is where today over two million people come to hike, camp, picnic, fish, hunt, and enjoy nature every year. However, the very geologic composition of Starved Rock and its environs has created a new challenge for the twenty-first century. Sand companies now mine silica sand near the park. The challenge is one of balance between protection of the park's fragile natural resources versus the competing interests of local governments and residents desiring new employment opportunities. In addition, the Starved Rock Dam, completed in 1933, raised the level of the Illinois River above the dam about ten feet. Nevertheless, the Illinois Department of Natural Resources employees at Starved Rock State Park are dedicated to preserving and maintaining the park and to serving park visitors.

This chapter illustrates the growing public interest in Starved Rock. Privately owned starting in 1835, Starved Rock was the domain of Daniel Hitt. In time, private development of the Starved Rock region grew. The adjacent property south and east of Starved Rock was purchased by private individuals, mainly farmers, industrious people whose labor brought forth the promise of the underdeveloped lands of Illinois that had years before been reclaimed by nature. In addition to tillable land, the farmers utilized erodible land for pasture to feed domestic livestock. In 1867, the US Army Corps of Engineers dispatched a party of cartographers to map the Illinois River. In September and October of 1883, another group of Army engineers under the supervision of W. H. H. Benyaurd surveyed the Illinois River. By the close of the nineteenth century, mining and industry were becoming an important part of the Starved Rock area's economy.

Infrastructural Power

In analysing the role of the US in the global expansion of capitalist relations, most critical accounts see the US military’s invasion and conquest of various states as paving the way for the arrival of US businesses and capitalist relations. However, beyond this somewhat simplified image, and even in peacetime, the US military has been a major geoeconomic actor that has wielded its infrastructural power via its US Army Corps of Engineers’ overseas activities. The transformation of global economies in the 20th century has depended on the capitalisation of the newly independent states and the consolidation of liberal capitalist relations in the subsequent decades. The US Army Corps of Engineers has not only extended lucrative contracts to private firms (based not only in the US and host country, but also in geopolitically allied states), but also, and perhaps most important, has itself established a grammar of capitalist relations. It has done so by forging both physical infrastructures (roads, ports, utilities and telecommunications infrastructures) and virtual capitalist infrastructures through its practices of contracting, purchasing, design, accounting, regulatory processes and specific regimes of labour and private property ownership.

Small Alteration

Calculations using the Neumann solution (as modified by Aldrich) and thermal properties of soils (obtained by Kersten) show that the frost penetration depth for the same freezing index for essentially all soils with any moisture content and for dry sand and rock varies by a factor of about 2 to 1. The extremes calculated in this way bracket the experimentally determined design curve of the US Army Corps of Engineers and give it theoretical support. The theoretical calculations and additional experimental data are used as a basis for a small alteration in the slope of the design curve. This modified design curve is recommended for field use because of (1) inherent imperfections in existing theory and (2) practical limitations to precise specification of field conditions.

Limited Application

An automated Coastal Model Test Bed has been built for the US Army Corps of Engineers Field Research Facility to evaluate coastal numerical models. In October of 2015, the test bed was expanded during a multi-investigator experiment, called BathyDuck, to evaluate two bathymetry sources: traditional survey data and bathymetry generated through the cBathy inversion algorithm using Argus video measurements. Comparisons were made between simulations using the spectral wave model STWAVE with half-hourly cBathy bathymetry and the more temporally sparse surveyed bathymetry. The simulation results using cBathy bathymetry were relatively close to those using the surveyed bathymetry. The largest differences were at the shallowest gauges within 250 m of the coast, where wave model normalized root-mean-square was approximately twice are large using the cBathy bathymetry. The nearshore errors using the cBathy input were greatest during events with wave height greater than 2 m. For this limited application, the Argus cBathy algorithm proved to be a suitable bathymetry input for nearshore wave modeling. cBathy bathymetry was easily incorporated into the modeling test bed and had the advantage of being updated on approximately the same temporal scale as the other model input conditions. cBathy has great potential for modeling applications where traditional surveys are sparse (seasonal or yearly).

This biography examines the long career of Lt. Gen. Edward M. Almond, who was born to a family of modest means in rural Virginia. His early education at the Virginia Military Institute, steeped him in Confederate lore and nurtured his “can do” attitude, natural aggressiveness, demanding personality and sometimes self-serving nature. These qualities later earned him the sobriquet “Sic’em, Ned,” which stuck with him for the remainder of his career. Almond commanded the African-American 92nd Infantry Division during World War II. The division failed in combat and was re-organized, after which it contained one white, one black, and the Army’s only Japanese-American (Nisei) regiment. The years since that war have seen the glorification of the “Greatest Generation,” with all racist notions and ideas “whitewashed” with a veneer of honor. When war came to Korea, Almond commanded X Corps in the Inchon invasion, liberation of Seoul, race to the Yalu. When the Chinese entered the war and sent the US Army into retreat, Almond mounted one of the largest evacuations in history at Hungnam -- but not before the disaster at Chosin claimed the lives of hundreds of soldiers and marines. This book reveals Almond as a man who stubbornly held onto bigoted attitudes about race, but also exhibited an unfaltering commitment to the military profession. Often viewed as the “Army’s racist,” Almond reflected the attitudes of the Army and society. This book places Almond in a broader context and presents a more complete picture of this flawed man yet gifted officer.

Over recent decades, three distinct methods have evolved that are currently being used to generate resistance functions for single-degree-of-freedom analyses of unreinforced masonry walls subjected to blast loading. The degree of differences in these resistance definitions depends on whether the wall is assumed to be simply supported or whether compression arching forces result from rotation restraint at the supports. The first method originated in the late 1960s as a result of both experimental and analytical research sponsored by the US Department of Defense. That method, referred to as the Wiehle method, is the basis of Unified Facilities Criteria 3-340-02 and other derived analytical software such as the Wall Analysis Code developed by the US Army Corps of Engineers, Engineer Research and Development Center. The second method is based on elastic mechanics and an assumed linear decay function that follows and is the basis of the widely used Single-Degree-of-Freedom Blast Effects Design Spreadsheets software distributed by the US Army Corps of Engineers, Protective Design Center. The third method is largely based on concrete and masonry behavioral theories developed by Paulay and Priestly in the early 1990s. This article systematically compares the resistance methodologies for arching and non-arching scenarios, demonstrates the implications by plugging the disparate resistance functions into blast load single-degree-of-freedom models, compares the analytical results to full-scale blast test results, and offers conclusions about the accuracy and efficacies of each method.
