The 20 chapters of The Geology of Washington and Beyond�an outgrowth of a geologic symposium�present the substantial advances in recent research on the geologic history of Washington State. The 32 contributors used new conceptual developments such as sequence stratigraphy, identification and matching of terranes, and neotechtonics, as well as breakthroughs in technology such as lidar mapping, paleomagnetism, and new methods of radiometric dating, to examine the fascinating geology of Washington State and beyond. Also included is geologic mapping in areas previously known only by reconnaissance. This book will influence resource management decisions, as well as disaster and land-use planning in the region. The introductory chapters make the book accessible for undergraduate courses in geology and to the general public.

The Physical Geography of South America, the eighth volume in the Oxford Regional Environments series, presents an enduring statement on the physical and biogeographic conditions of this remarkable continent and their relationships to human activity. It fills a void in recent environmental literature by assembling a team of specialists from within and beyond South America in order to provide an integrated, cross-disciplinary body of knowledge about this mostly tropical continent, together with its high mountains and temperate southern cone. The authors systematically cover the main components of the South American environment - tectonism, climate, glaciation, natural landscape changes, rivers, vegetation, animals, and soils. The book then presents more specific treatments of regions with special attributes from the tropical forests of the Amazon basin to the Atacama Desert and Patagonian steppe, and from the Atlantic, Caribbean, and Pacific coasts to the high Andes. Additionally, the continents environments are given a human face by evaluating the roles played by people over time, from pre-European and European colonial impacts to the effects of modern agriculture and urbanization, and from interactions with El Ni?o events to prognoses for the future environments of the continent.

In my book Introduction to High Altitude Entomology, published in 1962, I summa rized the results of eight years' studies, mainly on the Himalaya. I have since then had the opportunity of studying the collections of high altitude insects from the Alps, Carpathians, Caucasus, Urals, Alai-Pamirs, Tien Shan, Altai and other im portant mountains of the world in different museums and institutions in Europe. Through the courtesy and generosity of the Academy of Sciences of the Union of Soviet Socialist Republics, I was also able to personally collect insects and make valuable field observations on the Caucasus, the Alai-Pamirs, Ala-Tau and the Tien Shan mountains. Through comparative studies I have tried to synthesize the fundamental principles of high altitude entomology. I have described here the distinctive characters of the high altitude environment, the ecological specializations of the high altitude insects, their ecological inter relations and the outstanding peculiarities of their biogeography. I have also pre sented here an outline of the high altitude entomology of the principal mountains of the world, with brief accounts of their orogeny, geology and vegetation. This book differs from all other contributions in the field in its comparative ecological approach and in the fact that the main emphasis is throughout on the evolution of the high altitude ecosystem as an integral part of the orogeny. High mountains are, in all parts of the world, important and independent centres of origin and differ entiation of distinctive and highly specialized ecosystems and faunas.

This guide is based on our much larger (530-page) guide to Bolivia. Here we zero in on La Paz, The capital, and all of the nearby attractions. La Paz is not a big city on the world scale, but it is certainly one of the more interesting ones. Built in a bowl created by the Choqueyapu River, The upper parts of the city stand 1,645 ft/500 m above the lower sections. Unlike any other city in the world, The richer neighborhoods are located at the lower levels. This is partly due To The fact that it is warmer and easier to breathe at the lower altitudes. Also, The pinnacles and spires of conglomerate rock and clay that have been sculptured by wind and water make a dramatic backdrop for those living below them. The higher up the bowl one goes, The more unstable the land becomes And The more likely a landslide will occur. The plazas, squares and Prado are well kept in La Paz and even in the depth of winter plants are tended to help make the city attractive. Street cleaners are out every day and local merchants regularly wash the area in front of their shops. On a clear day, Mount Illimani, a snow-covered monolith, can be seen as a sentry towering over the city. Valley of the Moon is six miles/10 km from the center of La Paz and can be reached by joining a tour or by taking micro bus #11 or minibus #231 or 273 to Mallasilla. The hillside features a maze of clay canyons and pinnacles that have been sculpted by wind and rain. Narrow trails through the landscape take about an hour to walk. There is also a cactus park just before the entrance. The park overlooks a gorge and has paths leading around numerous types of cacti. As you continue up the road you will come to Parque National Mallasa with its bird observatory and, across the road, The zoo area. The road passes under natural stone bridges and past Chulpani's Red Hill. There is no mistaking which hill this is. From Mallasa one can see across the river To The highest golf course in the world. Devil's Tooth or Muela del Diablo is a huge volcanic plug sticking out of the landscape to a height of 13,000 ft/3,950 m. Several trails go To The right; follow the one that obviously leads To The village. From there, go To The left for .3 miles (about half a kilometer), To the foot of the rock. Climbers are occasionally found on the east face. Canyon de Palca, or Valle de Animas, Is a deep canyon that was carved by the Rio Palca centuries ago. To get there, take a bus going to Huni from Plaza Belzu on Avenida Mexico in San Pedro. There are huge pinnacles and wind-carved conglomerates. The trail continues along the bottom of the canyon to a natural obelisk. Just past the obelisk is a rock that has the appearance of a human hiding in a cave. The rock is called the hermit of the canyon. Continue along the canyon to its end and climb to your left up To The village of Palca. This is a long day-hike. All of the detailed information you need is here about the hotels, restaurants, shopping, sightseeing. But we also lead you to new discoveries, turning corners you haven't turned before, helping you to interact with the world in new ways. That's what makes our Adventure Guides unique. "An excellent addition To The Adventure Guide series, packed with detail, from where to stay and eat, To where to shop for local crafts and how to enjoy historic sites. This guide surveys the wildlife and outdoor opportunities of the country, which range from tropical jungle to high plains deserts. Hiking and viewing opportunities blend with cultural insights. Highly recommended." - The Midwest Book Review.
