"One of the world's great karstic aquifer systems, the Edwards aquifer system supplies water for more than 2 million people and for agricultural, municipal, industrial, and recreational uses. This volume reviews the current state of knowledge, current and emerging challenges to wise use of the aquifer system, and some technologies that must be adopted to address these challenges"--

The great earthen mounds of southern Ohio have attracted archaelogical attention since the first half of the nineteenth century. Until now, little has been known of the social organization of the Native Americans who constructed these spectacular ceremonial monuments. In the early 1960s, Olaf Prufer argued that the Ohio Hopewell societies who built the mounds that characterize the Middle Woodland Period (200 B.C. to A.D. 400) lived in a small, scattered hamlets. Prufer's thesis was evaluated at the symposium "Testing the Prufer Model of Ohio Hopewell Settlement Pattern" at the annual meeting of the Society for American Archaeology in Pittsburgh, April 10, 1992. Several of those essays and others, including two by Professor Prufer, are included in Ohio Hopewell Community Organization. Within the last decade, more than 100 instances of Middle Woodland domestic sites have been documented. The authors examine plant and animal remains, ceramic and stone fragments, and traces of structures and facilities recovered through survey and excavation. The essays illustrate many of the controversies revolving around scientific study of the Hopewellian lifeway. In an Afterword, James B. Griffin shows that the problem of Hopewellian settlement pattern has deep intellectual roots, and its solution will be significant not only for the Ohio Valley but for world prehistory as well. While the volume holds obvious interest for professional archaeologists, it will also appeal to amateur archaeologists and visitors to prehistoric sites and museums.

This volume 'Use ofMicrocomputers in Geology' is the sixth in the series Computer Applications in the Earth Sciences published by Plenum Press in New York. The series was started in 1969 to publish proceedings of important meetings on geomathematics and computer applications. The first two volumes recorded proceedings ofthe Colloquia (1969,1970) sponsored by the Kansas Geological Survey at The University ofKansas in Lawrence. The third volume was proceedings ofthe 8th International Sedimentological Congress (1971) held in Heidelberg, West Germany; the fourth was preceedings ofthe 8th Geochautauqua (1979) at Syracuse Universityin Syracuse, New York; and the fifth was selected papers from the 27th International Geological Congress (1989) held in Washington, D.C. All meetings were cosponsored by the International Association for Mathematical Geology. These special publications are important in the development of quantitative geology. Papers by a wide range of authors on a wide range of topics gives the reader a flavor for recent advances in the subject -in this volume, those advances in the use ofmicrocomputers. The 24 authors ofthe 15 papers come from nine countries -Australia, Austria, Canada, France, Italy, Portugal, Switzerland, UK, and USA. My coeditor, Hans Kürzl, has given pertinent information on the included papers in the Introduction.
