Book Description
Focusing on more than 30,000 years of Alaskan prehistory, The Ice-Age History of Alaskan National Parks vividly describes the geology, climate, ancient plant and animal life, and human presence in four of Alaska's national parks and preserves - Denali, Kenai Fjords, Glacier Bay, and Bering Land Bridge. Scott A. Elias uncovers a time when glaciers shaped the landscape, gouging out valleys, carving cirques and peaks, and leaving moraines that blocked rivers and formed lakes. Using fossils as "witnesses" of past environments, he recreates the bogs and steppe tundra where caribou, moose, saber-toothed cats, and mammoths reigned 35,000 years ago. This guidebook presents a unique perspective for the modern traveler. Geared toward the general reader, it is the first in a series that will also survey the prehistory of the Rocky Mountain and Southwest national parks.

Book Description
The demand for water resulting from massive population and economic growth in the southwestern U.S. overwhelmed traditional uses of riparian areas. As a consequence, many of these uniquely-structured ecosystems have been altered or destroyed. Within recent years people have become increasingly aware of the many uses and benefits of riparian zones a

Book Description
The Southern Andes, stretching from the subtropics to the subantarctic, are ideally located for palaeoenvironmental research. Over the broad and continuous latitudinal extent of the cordillera (-24˚), vegetation is adjusted to climatic gradients and atmospheric circulation patterns.Opposed to the prevailing Southern Westerlies, the Southern Andes are positioned to receive the brunt of the winds, while biota are set to record the shifting of incoming storm systems over time. Sequential, latitudinally-placed, sedimentary deposits containing microfossils and macroremains, as archives of past vegetation and climate, make possible the detection of equatorward and poleward displacement of plant communities and, as a consequence, changes in climatic controls. No terrestrial setting in the Southern Hemisphere is so unique for palaeoenvironmental reconstruction during and since the last ice age. Twenty radiocarbon-dated fossil pollen and spore records chosen to place emphasis on the last ice age include high-resolution, submillennial data sets that also cover the Holocene, thus providing contrast between present interglacial and past glacial ages. From a refined data base, the records constitute the foundation for interpreting factors responsible for vegetation change over >50,000 14C years, glacial-interglacial migration and refugial patterns for a diversity of taxa, and the extent of intrahemispheric and polar hemispheric synchroneity versus asynchroneity.

Book Description
The book presents an up-to-date, detailed overview of the Quaternary glaciations all over the world, not only with regard to stratigraphy but also with regard to major glacial landforms and the extent of the respective ice sheets. The locations of key sites are included. The information is presented in digital, uniformly prepared maps which can be used in a Geographical Information System (GIS) such as ArcView or ArcGIS. The accompanying text supplies the information on how the data were obtained (geomorphology, geological mapping, air photograph evaluation, satellite imagery), how the features were dated (14C, TL, relative stratigraphy) and how reliable they are supposed to be. All references to the underlying basic publications are included. Where controversial interpretations are possible e.g. in Siberia or Tibet, this is pointed out. As a result, the information on Quaternary glaciations worldwide will be much improved and supplied in a uniform digital format. The information on the glacial limits is compiled in digital form by the coordinators of the project, and is available for download at: http://booksite.elsevier.com/9780444534477/ Completely updated detailed coverage of worldwide Quaternary glaciations Information in digital, uniformly prepared maps which can be used in a GIS such as ArcView or ArcGis Step-by-step guideline how to open and use ArcGis files Possibility to convert the shapefiles into GoogleEarth kmz-files Availability of chronological controls
