Book excerpt: Excerpt from Geomorphic History of the Virgin River in the Zion National Park Area, Southwest Utah This study addresses the alluvial geo morphology of the upper Virgin River in southwest Utah during the past years, the late Holocene of geologic time. The study area lies in and near Zion National Park and includes the North Fork (virgin River) in Zion Canyon below The Narrows, East Fork (virgin River) in lower Parunuweap Canyon, and the Virgin River downstream of the park to Virgin, Utah (fig. The question of how natural variations of discharge and sediment load alter the alluvial valley and channel was the research topic. This information is necessary to understand the role of dis charge variability in the recent geomorphic development of the alluvial valley, which in turn effects riparian and aquatic resources. These resources are linked to changes in the alluvial valley, because alluvium is the sub strate for riparian vegetation and the allu vial channel is the habitat of six species of native fish (deacon, written commun., Results of this study suggest that the allu vial valley has changed rapidly in response to natural discharge variations.

Available in PDF, EPUB and Kindle. Book excerpt: Experience the wonderful beauty of Zion Canyon where the photography depicts a visual image of the canyon, while the story takes the reader on an epic historical journey through the region. The book is broken down into seven chronological chapters: the geological history--describes the numerous rock layers and events, including the Western Interior Seaway, that contributed to creating the Colorado Plateau; the early civilizations--recounts the Native Americans who inhabited the region; the explorers--portrays the expeditions of Dominguez/Escalante and Jedediah Smith parties that traversed Southern Utah; the Mormon settlers--gives an account of Brigham Young leading members from the Church of Jesus Christ of Latter Day Saints west to settle in the Utah Territory; the land survey of 1872--relates the exploration and land survey companies who formed the United States Geological Survey; proclamation for a new valley of wonders--sets forth the details for becoming a national monument; and Zion National Park--sums up becoming a national park from 1919 to present day.

Download or read book The Geology of the Central Virgin River Basin Southwestern Utah and Its Relation to Ground water Conditions written by Hugh A. Hurlow and published by Utah Geological Survey. This book was released on 1998-01-01 with total page 65 pages. Available in PDF, EPUB and Kindle. Book excerpt: This report describes the geology of the central Virgin River basin in southwestern Utah, and characterizes the structure and lithology of the Jurassic Navajo Sandstone and the thickness and stratigraphy of Quaternary-late Tertiary unconsolidated deposits, the two main aquifers in the region. Southwestern Utah has experienced rapid population growth and increased demand on water supplies during the past 15 years, and the purpose of this report is to better define the ground-water resources of the area. Ground water provides approximately half of the public water supply in southwestern Utah, so future decisions regarding water use must be based on careful geologic characterization of the aquifers and their relation to the regional hydrologic system. The results of this study will be applied to ground-water modeling, evaluating regional and local hydrogeologic conditions, and assessing sites for development of ground water. 53 pages + 7 plates
