  	Citation × Citation Citation Abstract Copy Title: Geological and Geothermal Investigation of the Lower Wind River Valley, Southwestern Washington Cascade Range Author: Berri, Dulcy A. Year: 1983 The Wind River Valley, on the west slope of the Cascade Range, is a northwest-trending drainage that joins the Columbia River near Carson, Washington. The region has been heavily dissected by fluvial and glacial erosion. Ridges have sharp crests and deep subsidiary valleys typical of a mature topography, with a total relief of as much as 900 m. The region is vegetated by fir and hemlock, as Well as dense, brushy ground-cover and undergrowth. The lower 8 km of the valley is privately owned and moderately populated. The upper reaches lies within the Gifford Pinchot National Forest, and include several campgrounds and day parks, the Carson National Fish Hatchery, and the Wind River Ranger Station and Wind River Nursery of the US Forest Service. Logging activity is light due to the rugged terrain, and consequently, most valley slopes are not accessible by vehicle. The realization that a potential for significant geothermal resources exists in the Wind River area was brought about by earlier exploration activities. Geologic mapping and interpretation was needed to facilitate further exploration of the resource by providing a knowledge of possible geologic controls on the geothermal system. This report presents the detailed geology of the lower Wind River valley with emphasis on those factors that bear significantly on development of a geothermal resource Title: Geological and Geothermal Investigation of the Lower Wind River Valley, Southwestern Washington Cascade Range Author: Berri, Dulcy A.

  	Citation × Citation Citation Abstract Copy Title: Beneficial Uses of Geothermal Energy Description and Preliminary Results for Phase 1 of the Raft River Irrigation Experiment Author: Schmitt, R.C. Year: 1977 The first phase of an experiment using geothermal water for irrigation is described and preliminary results are discussed. The water was from a moderate temperature well, having salinity of about 2000 ppM, and is considered characteristic of the types of geothermal fluids that will be obtained from the young volcanic/young sediment formations of the northern intermountain west. The activity was completed at a location adjacent to ERDA's Raft River Geothermal Project in southern Idaho. About 12.5 acres, of which part had no previous cultivation, were subdivided by crops and irrigation practices for investigation with the geothermal water and a control comparison water from the relatively pure Raft River. Flood and sprinkler application techniques were used and wheat, barley, oats, grasses, alfalfa, potatoes, and garden vegetables were successfully grown. An accompanying experiment evaluated the behavior of an established alfalfa crop located nearby, when most of the irrigation water was geothermal. The experiment addressed heavy metal uptake in plants, plant fluoride retention and damage, plant tolerances to salts, soil alterations and other behavior as a result of the geothermal fluids, all of which were largely believed to eliminate geothermal water from contention for crop growing utilization. Not all analyses and results are complete in this reporting, but first results indicate no apparent difference between the geothermal watered crops and those obtained using the fresh water control. Extensive chemical analyses, neutron activation analyses, and other evaluations of crop samples are discussed, and some of the findings are presented. Although evaluation of crop yields was not an objective, extrapolations from samples indicate that yield results were comparable to those commonly found in the area, and the yield varied little between water sources.
