USGS Geologic Investigations Series I-1963, Pamphlet
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. -

Tracing Subduction Zone Processes with Magnesium Isotopes
Tracing subduction zone processes with magnesium isotopes Yan Hu A dissertation submitted in partial fulfillment of the requirements for the degree of Doctor of Philosophy University of Washington 2018 Reading Committee: Fang-Zhen Teng, Chair Bruce K. Nelson Ronald S. Sletten Program Authorized to Offer Degree: Earth and Space Sciences © Copyright 2018 Yan Hu University of Washington Abstract Tracing subduction zone processes with magnesium isotopes Yan Hu Chair of the Supervisory Committee: Professor Fang-Zhen Teng Department of Earth and Space Sciences Subduction and recycling of oceanic plates change the chemical composition of mantle and affect its physical properties, thereby modulating Earth’s dynamics. Stable Mg isotopes (δ26Mg) can trace this recycling process as crustal materials are highly fractionated compared to the average mantle composition. This dissertation focuses on Mg isotope fractionation during subduction-related processes and the consequent mantle heterogeneity. The dissertation first compares inconsistent δ26Mg values of San Carlos peridotitic olivines that are published by several laboratories. We analyzed mineral grains from two San Carlos peridotites with disparate lithologies and determined that all mineral phases have indistinguishable δ26Mg values to within 0.07‰. With analytical precision and accuracy being confirmed, the significance of anomalous δ26Mg values can be understood in the context of mantle heterogeneity. The next paper investigates the Mg isotopic heterogeneity in mantle pyroxenites that have formed by multi-stage interactions between peridotites and melts with diverse origins. Pyroxenites formed by reaction with melts derived from subducted oceanic crust and carbonate sediments are shown to have variable δ26Mg values (−1.51‰ to −0.10‰). In contrast, pyroxenites that are formed by reaction with silicate melts from deep mantle has δ26Mg values similar to common mantle peridotites. -

The project’s authorized capacity is 111.8 megawatts (MW). The project is located on the Sultan River, 20 miles east of the City of Everett, Washington, in Snohomish County. The project occupies 10.9 acres of the Mount Baker-Snoqualmie National Forest administered by the U.S. Forest Service (Forest Service). Downstream of the project’s Culmback dam at Spada Lake, the Sultan River flows through a deep forested gorge for nearly 14 miles. The project powerhouse is located near the downstream end of the gorge. The District (Public Utility District No. 1 of Snohomish County) currently operates the project to satisfy the City of Everett’s municipal water supply needs, protect aquatic resources, maintain Spada lake levels for summer recreation, and generate electricity. The new license requires additional measures to protect and enhance water quality, fish, wildlife, recreation, and cultural resources. The twelve signatories to the Settlement Agreement are the District, National Marine Fisheries Service (NMFS), Forest Service; U.S. Fish and Wildlife Service (FWS), U.S. National Park Service, Washington Department of Fish and Wildlife (Washington DFW), Washington Department of Ecology (Ecology), Tulalip Tribes of Washington (Tulalip Tribes), Snohomish County, Washington; City of Everett; City of Sultan; and American Whitewater. -

The quadrangle is mostly rugged and remote and includes much of the North Cascade National Park and several dedicated Wilderness areas managed by the U.S. Forest Service. Geologic exploration has been slow and difficult. In 1858 George Gibbs (1874) ascended the Skagit River part way to begin the geographic and geologic exploration of the North Cascades. In 1901, Reginald Daly (1912) surveyed the 49th parallel along the Canadian side of the border, and George Smith and Frank Calkins (1904) surveyed the United States' side. Daly's exhaustive report was the first attempt to synthesize what has become an extremely complicated geologic story. -
