    Carson - Wind River Valley Water Supply by Ivan Donaldson Skamania County Historical Society Carson - Wind River Valley Water Supply

    Irrigation flume wends way from Panther Creek toward yet-to-be-built High Bridge over Wind River. Carson - Wind River Valley Water Supply By Ivan Donaldson Skamania County Historical Society Carson - Wind River Valley Water Supply By Ivan Donaldson Skamania County Historical Society E. J. Weigle home north of Carson. (This and other photos presented to Skamania County Historical Museum by Paul Boyd.) Much of the soil of the Carson Valley is a shallow sandy layer deposited on top of the geologically recent Trout Creek Olivine basalt lava flow. This is the lava flow which filled the Wind River canyon to a considerable depth, dammed the Columbia River, and created the Panther Creek reef or lava dike which is described later in this article. The soil, while fertile and productive, dries out quickly and crops grown in this valley require frequent watering in the summertime. Contra to this statement is the knowledge that the early strawberry fields produced well with no irrigation water. During the first decade of the 1900s, entrepreneur and promoter, B. M. Hawley of Home Valley, Washington, and his associates began action upon their dream to convert the heavily timbered Carson Valley into an agricultural paradise. These gentlemen indulged their expensive fantasy to inititate construction of an irrigation flume which to exrend from Panther Creek six to eight miles to the semi-level Carson Valley plain as we know it now in 1984. Carson Water Supply — Page 2 Skamania County records show that on 1 April 1907 B. M. Hawley filed for a water right on Panther Creek, tributary to Wind River, for 60 cubic feet per second of water, giving the point of diversion and stating it was for irrigation, power, and domestic use.

  • The Jackson Volcano

    The Jackson Volcano

    THE DEPARTMENT OF ENVIRONMENTAL QUALITY Office of Geology P. 0. Box 20307 Volume 18, Number 3 Jackson, Mississippi 39289-1307 September 1997 THE JACKSON VOLCANO David T. Dockery ID, John C. Marble, and Jack Henderson Mississippi Office of Geology INTRODUCTION One of the most interesting geologic features ofMississippi is the Jackson Volcano, which rests only 2900 feet beneath the state's capital city. The volcano's dense core forms one ofthe most prominent structural anomalies found on gravity and magnetic surveys of the state, showing tightly wrapped con­ tours of increasing gravity and magnetic deflection like a crowded bull's- eye (Figure l ). This igneous complex and the up Iifted formations around it comprise a structure known as the Jackson Dome. Northwest ofthe Jackson Volcano in southern Humphreys County is the Midnight Volcano and the associ­ ated volcanic terrain ofthe Sharkey Platform . Dense igneous rock below Jackson and Midnight increase the force ofgravity slightly as shown in Figure I. A person tipping the scales at Jackson or Midnight would be slightly heavier than elsewhere in the state (if anyone would like to use that for an excuse). No other capital city or major population center is situated above an extinct volcano, even though the recent movie "Volcano" fictitiously placed Los Angeles, California, above one. Monroe, Louisiana, is Jackson 's sister city in being a close second, as it rests above a volcanic terrain known as the Monroe Uplift. However, the position ofJackson's downtown district above the throat of an extinct Cretaceous volcano seems to be unique. Ifthe Jackson Volcano were to ever vent itself in the future, the Coliseum would be near ground zero.

    NEON Site-Level Plot Summary Wind River Experimental Forest (WREF)

    NEON Site-Level Plot Summary Wind River Experimental Forest (WREF) Document Information Date March 14, 2019 Author Erik Dahlke, Senior Regional Soil Scientist Soil Survey Region 1, Portland, OR Site Background The Wind River Experimental Forest NEON site (WREF) site is approximately 60 kilometers northeast of Vancouver in Skamania County, Washington. The WREF site is at the United States Forest Service (USFS) Pacific Northwest Research Station – Wind River Experimental Station in the Gifford Pinchot National Forest (GPNF). WREF covers roughly 10,360 acres within Major Land Resource Area 3 (MLRA 3) – Olympic and Cascade Mountains. Most of the area lacks a Natural Resources Conservation Service (NRCS) Soil Survey; a small portion occurs within the 1990 Soil Survey of Skamania County, Area, Washington (WA659). A USFS Soil Resource Inventory (SRI) is available for GPNF. This product, produced at a smaller scale than NRCS soil maps, provides inventory information for geology, landform, and slope, as well as general soil groupings. Site Information The WREF site has varied relief. Elevation and slope ranges were derived from a digital elevation model (DEM), and range from slightly less than 300 meters to over 1275 meters; slope gradients range from 0 to more than 90 percent. Mean annual precipitation is between 2200 millimeters to about 3000 millimeters based on data from the PRISM (Parameter-elevation Regression on Independent Slopes Model) Climate Group at Oregon State University. The WREF site consists of two distinct land areas referred to here as the ‘East Unit’ and ‘West Unit’. The West Unit contains the NEON instrument tower and all but six of the NEON distributed plots.

This explosion was the most powerful in a series of eruptions during 1914–17 that were the last to occur in the Cascade Range before the 1980 eruption of Mount St. Helens, Washington. A century after the Lassen eruptions, work by U.S. Geological Survey (USGS) scientists in cooperation with the National Park Service is shedding new light on these events.

It is not prominently visible from any major popu- lation center, and so its attractions, as well as its hazards, tend to be over- looked. Yet since the end of the last ice age, Glacier Peak has produced some of the largest and most explosive eruptions in the state. During this time period, Glacier Peak has erupted multiple times during at least six separate Baker episodes, most recently Pacific Ocean about 300 years ago.

  • Lassen Peak Trail

    Lassen Peak Trail

    L A Lassen Peak Trail Zig-zagging 2.2 miles to the top of one of the world's largest plug domes, the Lassen Peak Trail offers magnificent vistas of a land of vol­ £ canoes, mountain forests and sparkling lakes. Four types of volcanoes can be seen from the trail. The summit of the peak is crowned by several craters and the lava flow of 1915. A round trip takes about four hours for the average person. A slow E pace is advised at this elevation (8,500 to 10,457). For your comfort, take suntan lotion, dark glasses, a hat, water and a wind breaker. Be prepared for strong winds at the summit, even though it may be calm when you "start on your trip. PLEASE stay on the trail. N The Circle of Fire Lassen Peak lies at the southern tip of the Cascade Range, a series of volcanic mountains that extend through Northern California, Oregon, Washington and on into Canada. Lassen and the Cascade Range are in turn a part of the Circle of Fire, a series of volcanoes that ring the Pacific Ocean. They owe their existence to the drifting of the con­ P tinents upon the earth's crust. Thus, Asia and America are moving closer together and overriding the floor of the Pacific Ocean. Tremendous forces are at work, faults occur and molten material, per­ haps from the ocean floor that has dipped below the Pacific Coast, can E return to the earth's surface as lava. Today the Lassen region is a land of earthquakes and volcanoes, but it has not always been so.
