The flows originated from Range. Many basaltic shield volcanoes, and cinder cones, two north-trending fissure zones: a west fissure, extending scattered among the higher cones, give evidence of long 30 km, with 11 distinct centers, which produced at least and perhaps more frequent volcanic activity. The Quaternary 14 groups of lava flows; and an east fissure, lying about basaltic volcanic field in the southern Cascade Range of 25 km to the east, passing beneath Mount Adams, and Washington is such an example. extending 48 km. The east fissure contains 8 centers, Basaltic volcanic fields have been considered unfavorable excluding the andesitic Mount Adams volcano, from which for geothermal resources. Because these fields are underlain at least 10 groups of lava have flowed.

  • 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.

Low-relief rocky meadows and modest forested ridges marked by scattered cinder cones and shields are common landforms in Simcoe Mountains volcanic field. Mount Adams (elevation: 12,276 ft; 3,742 m) is centered 50 km west and 2.8 km higher than foreground meadow (elevation: 2,950 ft.; 900 m); its eruptions began ~520 ka, its upper cone was built in late Pleistocene, and several eruptions have taken place in the Holocene. Signal Peak (elevation: 5,100 ft; 1,555 m), 20 km west of camera, is one of largest and highest eruptive centers in Simcoe Mountains volcanic field; short-lived shield, built around 3.7 Ma, is seven times older than Mount Adams. 2015 U.S. Department of the Interior U.S. Geological Survey Contents Introductory Overview for Non-Geologists ...............................................................................................1 Introduction.....................................................................................................................................................2 Physiography, Environment, Boundary Surveys, and Access ......................................................6 Previous Geologic
