    U.S. DEPARTMENT OF THE INTERIOR TO ACCOMPANY MAP I-1963 U.S. GEOLOGICAL SURVEY GEOLOGIC MAP OF THE SKYKOMISH RIVER 30- BY 60 MINUTE QUADRANGLE, WASHINGTON By R.W. Tabor, V.A. Frizzell, Jr., D.B. Booth, R.B. Waitt, J.T. Whetten, and R.E. Zartman INTRODUCTION From the eastern-most edges of suburban Seattle, the Skykomish River quadrangle stretches east across the low rolling hills and broad river valleys of the Puget Lowland, across the forested foothills of the North Cascades, and across high meadowlands to the bare rock peaks of the Cascade crest. The quadrangle straddles parts of two major river systems, the Skykomish and the Snoqualmie Rivers, which drain westward from the mountains to the lowlands (figs. 1 and 2). In the late 19th Century mineral deposits were discovered in the Monte Cristo, Silver Creek and the Index mining districts within the Skykomish River quadrangle. Soon after came the geologists: Spurr (1901) studied base- and precious- metal deposits in the Monte Cristo district and Weaver (1912a) and Smith (1915, 1916, 1917) in the Index district. General geologic mapping was begun by Oles (1956), Galster (1956), and Yeats (1958a) who mapped many of the essential features recognized today. Areas in which additional studies have been undertaken are shown on figure 3. Our work in the Skykomish River quadrangle, the northwest quadrant of the Wenatchee 1° by 2° quadrangle, began in 1975 and is part of a larger mapping project covering the Wenatchee quadrangle (fig. 1). Tabor, Frizzell, Whetten, and Booth have primary responsibility for bedrock mapping and compilation.

  • The Bearhead Rhyolite, Jemez Volcanic Field, NM
    Journal of Volcanology and Geothermal Research 107 32001) 241±264 www.elsevier.com/locate/jvolgeores Effusive eruptions from a large silicic magma chamber: the Bearhead Rhyolite, Jemez volcanic ®eld, NM Leigh Justet*, Terry L. Spell Department of Geosciences, University of Nevada, Las Vegas, NV, 89154-4010, USA Received 23 February 2000; accepted 6 November 2000 Abstract Large continental silicic magma systems commonly produce voluminous ignimbrites and associated caldera collapse events. Less conspicuous and relatively poorly documented are cases in which silicic magma chambers of similar size to those associated with caldera-forming events produce dominantly effusive eruptions of small-volume rhyolite domes and ¯ows. The Bearhead Rhyolite and associated Peralta Tuff Member in the Jemez volcanic ®eld, New Mexico, represent small-volume eruptions from a large silicic magma system in which no caldera-forming event occurred, and thus may have implications for the genesis and eruption of large volumes of silicic magma and the long-term evolution of continental silicic magma systems. 40Ar/39Ar dating reveals that most units mapped as Bearhead Rhyolite and Peralta Tuff 3the Main Group) were erupted during an ,540 ka interval between 7.06 and 6.52 Ma. These rocks de®ne a chemically coherent group of high-silica rhyolites that can be related by simple fractional crystallization models. Preceding the Main Group, minor amounts of unrelated trachydacite and low silica rhyolite were erupted at ,11±9 and ,8 Ma, respectively, whereas subsequent to the Main Group minor amounts of unrelated rhyolites were erupted at ,6.1 and ,1.5 Ma. The chemical coherency, apparent fractional crystallization-derived geochemical trends, large areal distribution of rhyolite domes 3,200 km2), and presence of a major hydrothermal system support the hypothesis that Main Group magmas were derived from a single, large, shallow magma chamber.

To this end, this report discusses extent of available volcanic and tectonic data for the Basin and Range Physiographic Province, assesses usefulness of these data for constraining conceptual models of tectonism and associated volcanism in the Basin and Range, and addresses use of nonlinear dynamics for analyzing patterns of volcanism. Based on data from review of existing literature, the following conclusions and recommendations are drawn to provide guidance for future work in the remaining tasks of this project: (i) middle to late Cenozoic (i.e., less than 55 million years ago) volcanism in the Basin and Range Province can be broadly correlated

  • Climate Change Vulnerability and Adaptation in the Intermountain Region Part 1
    United States Department of Agriculture Climate Change Vulnerability and Adaptation in the Intermountain Region Part 1 Forest Rocky Mountain General Technical Report Service Research Station RMRS-GTR-375 April 2018 Halofsky, Jessica E.; Peterson, David L.; Ho, Joanne J.; Little, Natalie, J.; Joyce, Linda A., eds. 2018. Climate change vulnerability and adaptation in the Intermountain Region. Gen. Tech. Rep. RMRS-GTR-375. Fort Collins, CO: U.S. Department of Agriculture, Forest Service, Rocky Mountain Research Station. Part 1. pp. 1–197. Abstract The Intermountain Adaptation Partnership (IAP) identified climate change issues relevant to resource management on Federal lands in Nevada, Utah, southern Idaho, eastern California, and western Wyoming, and developed solutions intended to minimize negative effects of climate change and facilitate transition of diverse ecosystems to a warmer climate. U.S. Department of Agriculture Forest Service scientists, Federal resource managers, and stakeholders collaborated over a 2-year period to conduct a state-of-science climate change vulnerability assessment and develop adaptation options for Federal lands. The vulnerability assessment emphasized key resource areas— water, fisheries, vegetation and disturbance, wildlife, recreation, infrastructure, cultural heritage, and ecosystem services—regarded as the most important for ecosystems and human communities. The earliest and most profound effects of climate change are expected for water resources, the result of declining snowpacks causing higher peak winter

  • Bird Notes from Northern Michigan
    GENERAL NOTES BIRD NOTES FROM NORTHERN MICHIGAN In a recent paper (1948) I have detailed in part the results of a wildlife survey of the Huron Mountain district, Marquette County, Michigan, made from October 1939 to July 1942. Included therein are a description of the area and an inventory of its vertebrate fauna, among which are listed 206 species and subspeciesof birds, with only the briefest of notes appended. Certain additional data of special interest as well as Huron Mo&tain records of some forms not to my knowledge previously published are presented. Mentioned in the present notes are 29 species. Common Loon. Gavia immer.-This is a common summer resident, and pairs may be found on most of the inland lakes. On June 25, 1940, I located a nest containing 3 eggs (2 is the usual number) on a small island in Howe Lake. On June 26, 1912, at Mountain Lake I observed 2 chicks riding on the parent’s back. From July to October groups of from 2 to 6 loons are frequently seen on Lake Superior, near the shore, usually in early morning or evening. Blue Goose. Chen caevuZescens.-Bayard H. Christy has told me that 2 geese, seen on the Cranberry Marsh by Herbert E. Perkins in May 1926, were accurately described as this species. -American Pintail. Anus an&.-This species has been reported once in the Huron Moun- tains, on September 28 (probably since 1930), by B. H. Christy. Gadwall. Anus strepem-S. Morris Pell observed 1 of these ducks on Howe Lake on September 2, 1941.

  • The Advisability and Feasibility of Developing USP Standards for Medical Cannabis Gabriel I
    STIMULI TO THE REVISION PROCESS Stimuli articles do not necessarily reflect the policies of the USPC or the USP Council of Experts The Advisability and Feasibility of Developing USP Standards for Medical Cannabis Gabriel I. Giancaspro, Nam-Cheol Kim, Jaap Venema, Susan de Mars, Jennifer Devine, Carlos Celestino, Christine E. Feaster, Ben A. Firschein, Mary S. Waddell, Stephen M. Gardner, and Earl Jones Jr.a ABSTRACT This Stimuli article analyzes the need for public quality standards for medical cannabis (defined herein as marijuana used for medical purposes under state laws) and the potential role of the U.S. Pharmacopeial Convention (USP) in addressing that need.1 Following legalization of the medical use of cannabis in several U.S. states and internationally, USP has received requests to investigate the advisability and feasibility of developing quality standards for medical cannabis. Development of quality standards for medical cannabis requires consideration of a wide range of scientific, legal, and policy issues that reach far beyond its classification as a botanical drug or herbal medicine. This article discusses the current regulatory and scientific landscape regarding medical cannabis, identifies issues related to the lack of quality standards for medical cannabis, and explores potential options for developing quality standards. USP seeks input from stakeholders on whether USP should proceed with development of quality standards for medical cannabis and if so, what approaches should be utilized to establish such standards. LEGAL AND REGULATORY LANDSCAPE The federal and state regulatory environment surrounding the medical use of cannabis involves many federal agencies and various different state laws. The evolving legal environment is an important consideration when evaluating the advisability and feasibility of USP developing a public standard for cannabis.
