    The Yakima River Basin in south-central Washington has a long history of irrigated agriculture and a more recent history of large-scale livestock operations, both of which may contribute nutrients to the groundwater system. Nitrate concentrations in water samples from shallow groundwater wells in the lower Yakima River Basin exceeded the U.S. Environmental Protection Agency drinking-water. The U.S. Geological Survey. Along the Journey - May 4, Blue Mountains: The topography of the Blue Mountains consists of flat-topped ridges and steep stair-stepped valley walls formed by thousands of feet of Miocene basalt flows that engulfed the folded, faulted, and uplifted granitic core of the mountains.

    The Yakima River basin aquifer system underlies about 6, square miles in south-central Washington. The aquifer system consists of basin-fill deposits occurring in six structural-sedimentary basins, the Columbia River Basalt Group (CRBG), and generally older bedrock. Overview The gentle Yakima River winds for 27 miles through massive basalt cliffs and rolling desert hills between Ellensburg and Yakima, Washington. This area is popular for wildlife viewing, fishing, and floating the river. Recreation The Yakima River Canyon is a popular destination for plant and wildlife viewing, including bighorn sheep, various birds of prey, and mule deer.

Of flows which probably corresponds with the Yakima Basalt. Yakima Basalt is used here in the sense of Smith's original definition, because most Washington book the flows of the Vantage-Priest Rapids area, in the central part of the Plateau, ore definitely cor­ relatable with those of Smith's type section in Yakima Canyon.

Rock Content The base of the. Flows of the so-called “Columbia River Basalt Group” covered virtually all of Washington state east of the Cascades and south of a line roughly following the Spokane River, Lake Roosevelt, and the Columbia River from Grand Coulee Dam until the river makes its bend at Pateros.

The thickest sequence of basalt exposed in the study area is on the steep, northeastern slope of Rattlesnake Mountain; about meters of stratigraphic section can be examined in the field area. Subsidence and weak deformation of the southwestern Pasco Basin area during Yakima time can be recognized in the disposition of flows and interbeds.

The Vantage unit is located in the northeast, central, south, and southeastern part of the Yakima River Basin aquifer system and encompasses an area of about 3, mi 2.

The Yakima Basin Integrated Water Management Plan offers a commonsense approach to solving decades of water conflicts in the Yakima River Basin. It offers a year vision for responding to drought and changing climate, assuring water is clean and ample, and lands are both protected and productive.

The total volume of the volcanic province iscubic km. Eruptions filled the Pasco Basin in the east and then sent flows westward into the Columbia River Gorge. About 85% of the province is made of the Grande Ronde Basalt with a volume ofcubic km (enough lava to bury all of the continental United States under 12 m of lava!) that.

Andesite flow breccia, andesite flows, and minor tuff beds; includes some basalt flows and flow breccia. Commonly more massive and less altered than similar-appearing Eocene-Oligocene volcanic rocks. Clastic flows and flows of black glass, and course to fine-grained clastic and pyroclastic rocks in the Republic and Curlew areas of Ferry County.

The Grande Ronde Basalt subgroup comprises about 85% of the total volume of the CRBG. Individual flows are claimed to be similar, but distinctive enough from other flows, to correlate over most of the area. The CRBG averages km deep with a maximum depth of km in the Pasco Basin, generally the center of the area.

Flat-lying basalt flows cover most of southeastern Washington, northern Oregon, and western Idaho (Fig. Southwest from the Pasco Basin in the central Washington Columbia Basin, the basalt. The flows now cover approximatelysquare miles and total ab cubic miles of basalt.

On the basis of geophysical evidence, the basalts are known to reach a maximum thickness of 16, feet in the Pasco Basin. Twenty-one of these flows poured through the Gorge, forming layers of rock up to feet thick. The Yakima Fold Belt Subprovince covers ~14, km 2 of the western Columbia Basin and formed as basalt flows and intercalated sediments were folded and faulted under north-south directed compression.

Most of the present structural relief in the Columbia Basin has developed since ca. Ma, when the last massive outpouring of lava, the. Up to feet of the upper Miocene-lower Pliocene Yakima Basalt of the Columbia River Group underlie much of the eastern flank of the Cascade Range in the Tieton River area, Yakima County, Washington.

Local prebasalt relief was more than feet, so thicknesses of each of the 15 exposed flows vary widely. Single flows can be traced for many miles, and terminate only against local. tholeiitic flood basalt flows that cover an area of more t mi2 in Washington, Oregon, and western Idaho (Tolan et al., ) with a maximum thickness of o feet occurring in the Pasco Basin area (Reidel et al.,a, b).

Traveling west on I, you pass through amazing basalt columns, the granitic hills around Cheney and Sprague Lake (a large, flood-scoured basin). Yakima River Basin, the headwater areas in the Cascade Range include metamorphic, sedimentary, and intrusive and extrusive igneous rocks.
