The national economic effects of breaching the Lower Snake River Dams
The four Lower Snake River Dams have been providing irrigation, recreation, navigation, and electricity generation capabilities to residents of the Northwest since their completion in 1975. Meanwhile, salmon populations have gradually been declining to the point that five species of Snake River …

Irrigator Responses to Changes in Water Availability in Idaho's Snake River Plain
… changes in water availability in Idaho's Snake River Plain over the past 33 years. Google Earth Engine's high performance cloud computing and big data processing capabilities were used to compare the performance of three spectral indices, three compositing algorithms and two sensors for …

Predation, turbidity, and other factors influencing juvenile Salmonid survival in the lower Snake River
… is crucial because the construction of the Snake River hydrosystem has created a series of reservoirs, which have altered the river 's flow regimes, riparian vegetation, and turbidity. Further, several non-native fishes have been introduced as sport fish into the Lower Snake River. This …

Late Holocene Paleoflood Hydrology of the Snake River in the Lower Hells Canyon, Idaho
<p>The Snake River watershed spans a large geographic region from the Rocky Mountains to the inland Pacific Northwest, and a comprehensive paleoflood chronology on the mainstem of the river is key to identifying the frequency and magnitude of large prehistoric floods within the region. We examined …

Relationships Between Snake River Paleofloods, Occupational Patterns and Archaeological Preservation at Redbird Beach Archaeological Site in Lower Hells Canyon, Idaho
<p>The Snake River basin drains 282,000 km<sup>2</sup> of the northwestern U.S. and is the largest tributary to the Columbia River. Redbird Beach, an archaeological site located in the lower Hells Canyon reach of the Snake River, contains extensive vertical exposures of archaeological materials …

A small look at the big picture: linking geopotential height anomalies to paleofloods on the Snake River, Idaho and Oregon
… and flood hydroclimatology study on the Snake River in Idaho and Oregon suggests a link between floods and patters of geopotential height anomalies over the North Pacific Ocean. Examination of the paleoflood record in two 4-m (12 ft) tall terraces along the Hells Canyon reach of the Snake …

The Phylogeography of Prosopium in Western North America
… from the Bonneville Basin, the Columbia River Sub-basin, the lower Snake River Sub-basin, the upper Snake River Sub-basin, the Green River Basin, the Lahontan Basin, and the Missouri Basin were examined to test for geographically based genetic differentiation between drainage basins and …

Gastropods in lower Snake River and three of its tributaries and the effects of competition with the New Zealand mud snails (Potamopyrgus antipodarum)
… snails (Potamopyrgus antipodarum) in the lower Snake River and three tributaries and to determine if this invasive snail is competing with native gastropods. Potamopyrgus antipodarum is a successful invader in much of the Western United States and has been shown to impact nutrient cycling and …

Evaluation of Paleo-climate for the Boise Area, Idaho, from the last Glacial Maximum to the Present Based on delta 2H and delta 18O Groundwater Composition
… and divides the batholith from the western Snake River Plain. The Nampa-Caldwell system is in the volcanic, fluvial and pluvial sediments of the western Snake River Plain. Groundwater ages for these systems are modern, 5-15 ka, 10-20 ka, and 20-40 ka respectively. Local meteoric water lines …

Late Cenozoic basalts from the Basin-Range province, western United States
… Cenozoic basalts from adjacent regions (Columbia River Plateau, Snake River Plain, Yellowstone area, High Cascades and Sierra Nevada) are predominantly tholeiitic. This apparent petrologic provincialism is supported by complementary variations in heat flow, seismic velocities, crustal thickness, …

Testing the hypothesis of the slab-plume interaction on the formation of the Yellowstone hotspot system
… province that includes the mid-Miocene Columbia River flood basalt (CRFB) and subsequent Yellowstone and Newberry hotspot tracks. We find that the sinking slabs dominate the buoyancy and dynamics of the system, and that evolution of the mantle upwelling is subject to that of the slabs. Our …

Microstructural evolution of silicate immiscible liquids in solidifying ferrobasalts
… tholeiitic basaltic glass from Hawaii (USA), the Snake River Plain (USA), and the Laki eruption (Iceland). High-resolution imaging, electron probe microanalysis, and atom probe tomography are combined to examine the role played by compositional boundary layers in promoting unmixing around growing …

Variations in δ56Fe during magma differentiation at Cedar Butte volcano: signatures of thermal diffusion?
The Snake River Plain (SRP) is a volcanically active region lying along the Yellowstone hot spot track. Cedar Butte is a SRP volcanic complex which erupted a compositional progression of lavas from initial high silica rhyolite to final basaltic trachyandesite in the late pleistocene (~0.4 Ma). The …

Integrating apatite (U-Th)/He and fission track dating for a comprehensive thermochronological analysis: refining the uplift history of the Teton Range
… Jackson Hole valley and a portion of the Snake River. Relative to the rest of the Rocky Mountains, the Tetons experienced the majority of uplift very recently, substantiating the need for a detailed investigation integrating structural analysis and bedrock thermochronometry. New …
