Prehistory Of Long Valley, Idaho, United States Department Of Agriculture, Forest Service

Archaeology/Anthropology

This thesis deals with a group of artifact collections gathered by local amateurs from a series of sites along the western shoreline of Cascade Reservoir. This study uses these artifacts as a basis to put together a preliminary view of Long Valley prehistory. Outlines of the basic artifact types are formulated and placed into a chronology based upon typological comparisons and obsidian hydration. Previous archaeological work, the ethnohistory, and local geology of the valley are discussed and related ot the sites, used in this study, in order to determine their patterns and characteristics. From these efforts directions for further research …

The High Plains aquifer, which underlies about 174,000 square miles in parts of eight States, is the principal source of water in one of the Nation's major agricultural areas. About 170,000 wells pump water from the aquifer to irrigate about 13 million acres in the High Plains. In 1978, the U.S. Geological Survey began a regional study of the High Plains aquifer to provide geohydrologic data and computer models of the aquifer needed to evaluate the effects of ground-water development. This report describes the geohydrology of the High Plains aquifer. The High Plains aquifer consists mainly of hydraulically connected geologic …
