Mapping of Major Latest Pleistocene to Holocene Eruptive Episodes from the Glacier Peak Volcano, Washington—A Record of Lahar MAPPING OF MAJOR LATEST PLEISTOCENE TO HOLOCENE ERUPTIVE EPISODES FROM THE GLACIER PEAK VOLCANO, WASHINGTON—A RECORD OF LAHARIC INUNDATION OF THE PUGET LOWLANDS FROM DARRINGTON TO THE PUGET SOUND 123° 122° 121° 49° Benjamin W. Stanton and Joe D. Dragovich, Washington Department of Natural Resouces, Division of Geology and Earth Resources, 1111 Washington St SE, Olympia, WA 98504-7007, [email protected] and [email protected] map area Bellingham SAN WHA TCOM 20 JUAN Volcanic hazards in the Pacific Northwest are typically associated with more visible stratovolcanoes, such as Mount Rainier. Glacier Peak, a North Cascade dacitic stratovolcano near Darrington, Washington, has produced at least three large eruptive episodes See Figure 2 14 path of lahars since the culmination of the last continental glaciation with each episode likely lasting a few hundred years. Data from recent detailed geologic mapping, new C ages, stratigraphic relations, clast petrographic analyses, geochemical analyses, and laharic SKAGIT to lower Skagit Valley ISLAND sand composition indicate that three large eruptive episodes occurred in the latest Pleistocene and Holocene—the information refines and expands on the pioneering work of Beget (1981). These voluminous events traveled up to 135 km downvalley of the path of lahars to lower Stillaguamish Valley Glacier Peak edifice and reached the Puget Sound via the ancient Skagit and Stillaguamish deltas. Glacier Peak has erupted dacite of similar composition throughout its history. Hypersthene-hornblende-(augite)-phyric vesicular lahar clasts found from Glacier Peak to La volcano 48° SNOHMISH Conner, Washington have similar geochemistry to dacite flows sampled on the volcano. Radiocarbon dating of the White Chuck assemblage shows an eruptive episode of ~11,900 yrs B.P. This implies ice occupation during part of the White Chuck event and is 5 further supported by mapped deposits of the White Chuck assemblage that directly overlie recessional outwash along high inset terraces. Charcoal obtained from the Kennedy Creek assemblage yielded 14C ages of ~5,000 yrs B.P. Near La Conner, Washington, 14 KITSAP Seattle KING the Kennedy Creek lahar runout is locally interbedded with mid-Holocene estuarine and deltaic sediments of the Skagit delta. The Chocolate Creek assemblage yielded many C ages of ~1,800 yrs B.P. This assemblage occurs as the lowest and most inset lahar terrace near Darrington. Log-bearing flood deposits near Padilla Bay are 120 km from the edifice and contain dacitic sands and silts. This may be the most distal deposit of the Chocolate Creek complex. Many cities downvalley of Glacier Peak are built on Figure 1. Location of the study area as shown by the gray-shaded area (Figure 2). The arrows depict the river terraces comprised of lahar, lahar runout (hyperconcentrated flood deposits) and volcanic alluvium. Although Glacier Peak is generally not visible from urban areas, it is an active volcano that periodically erupts in an explosive manner. This could affect paths of Glacier Peak lahars and lahar runout that Figure 18.

  • Suspended-Sediment Concentration in the Sauk River, Washington, Water Years 2012-13
    Prepared in cooperation with the Sauk-Suiattle Indian Tribe Suspended-Sediment Concentration in the Sauk River, Washington, Water Years 2012-13 By Christopher A. Curran1, Scott Morris2, and James R. Foreman1 1 U.S. Geological Survey, Washington Water Science Center, Tacoma, Washington 2 Department of Natural Resources, Sauk-Suiattle Indian Tribe, Darrington, Washington Photograph of glacier-derived suspended sediment entering the Sauk River immediately downstream of the Suiattle River mouth (August 5, 2014, Chris Curran). iii Introduction The Sauk River is one of the few remaining large, glacier-fed rivers in western Washington that is unconstrained by dams and drains a relatively undisturbed landscape along the western slope of the Cascade Range. The river and its tributaries are important spawning ground and habitat for endangered Chinook salmon (Beamer and others, 2005) and also the primary conveyors of meltwater and sediment from Glacier Peak, an active volcano (fig. 1). As such, the Sauk River is a significant tributary source of both fish and fluvial sediment to the Skagit River, the largest river in western Washington that enters Puget Sound. Because of its location and function, the Sauk River basin presents a unique opportunity in the Puget Sound region for studying the sediment load derived from receding glaciers and the potential impacts to fish spawning and rearing habitat, and downstream river-restoration and flood- control projects. The lower reach of the Sauk River has some of the highest rates of incubation mortality for Chinook salmon in the Skagit River basin, a fact attributed to unusually high deposition of fine-grained sediments (Beamer, 2000b).

  • Where the Water Meets the Land: Between Culture and History in Upper Skagit Aboriginal Territory
    Where the Water Meets the Land: Between Culture and History in Upper Skagit Aboriginal Territory by Molly Sue Malone B.A., Dartmouth College, 2005 A THESIS SUBMITTED IN PARTIAL FULFILLMENT OF THE REQUIREMENTS FOR THE DEGREE OF DOCTOR OF PHILOSOPHY in The Faculty of Graduate and Postdoctoral Studies (Anthropology) THE UNIVERSITY OF BRITISH COLUMBIA (Vancouver) December 2013 © Molly Sue Malone, 2013 Abstract Upper Skagit Indian Tribe are a Coast Salish fishing community in western Washington, USA, who face the challenge of remaining culturally distinct while fitting into the socioeconomic expectations of American society, all while asserting their rights to access their aboriginal territory. This dissertation asks a twofold research question: How do Upper Skagit people interact with and experience the aquatic environment of their aboriginal territory, and how do their experiences with colonization and their cultural practices weave together to form a historical consciousness that orients them to their lands and waters and the wider world? Based on data from three methods of inquiry—interviews, participant observation, and archival research—collected over sixteen months of fieldwork on the Upper Skagit reservation in Sedro-Woolley, WA, I answer this question with an ethnography of the interplay between culture, history, and the land and waterscape that comprise Upper Skagit aboriginal territory. This interplay is the process of historical consciousness, which is neither singular nor sedentary, but rather an understanding of a world in flux made up of both conscious and unconscious thoughts that shape behavior. I conclude that the ways in which Upper Skagit people interact with what I call the waterscape of their aboriginal territory is one of their major distinctive features as a group.

  • Cultural Resources Assessment for the Mount Vernon Downtown Flood Protection Project Mount Vernon, Skagit County, Washington
    CULTURAL RESOURCES ASSESSMENT FOR THE MOUNT VERNON DOWNTOWN FLOOD PROTECTION PROJECT MOUNT VERNON, SKAGIT COUNTY, WASHINGTON BY MARGARET BERGER AND SUSAN MEDVILLE GLENN D. HARTMANN, PRINCIPAL INVESTIGATOR PREPARED FOR: PACIFIC INTERNATIONAL ENGINEERING PO BOX 1599 EDMONDS, WA 98020 TECHNICAL REPORT #342 CRC PROJECT #0711I CULTURAL RESOURCE CONSULTANTS, INC. 8001 DAY ROAD WEST, SUITE B BAINBRIDGE ISLAND, WA 98110 FEBRUARY 28, 2008 Executive Summary This report describes a cultural resources assessment for the Mount Vernon Downtown Flood Protection Project, in Mount Vernon, Skagit County, Washington. This assessment was conducted at the request of the City of Mount Vernon. This report is intended to serve as a component of preconstruction environmental review in accordance with Section 106 of the National Historic Preservation Act (NHPA), as amended. The project consists of modifications to the existing flood protection system. Project plans include raising the existing earthen levee, installing new levee and floodwall segments in some locations, and a new ring dike around the Mount Vernon Wastewater Treatment Plant. To accommodate levee improvements, seven downtown commercial buildings and a residence will be razed. Assessment methods included a review of relevant background literature and maps, archaeological field reconnaissance survey and testing, and a historic building survey. There are no archaeological sites recorded within the project. Archaeological testing conducted using a backhoe revealed thick alluvial deposits overlain, in places, by fill. No indications of buried archaeological sites were observed, and the project is considered to have a low potential to affect as-yet unknown cultural resources. No further archaeological investigations are recommended prior to commencement of the project.

    SKAGIT COOPERATIVE WEED MANAGEMENT AREA Upper Skagit Knotweed Control Program 2013 Season Ending Report Sauk River during 2013 knotweed surveys. Prepared by: Michelle Murphy Stewardship Manager Skagit Fisheries Enhancement Group PO Box 2497 Mount Vernon, WA 98273 Introduction In the 2013 season, the Skagit Fisheries Enhancement Group (SFEG) and our partners with the Skagit Cooperative Weed Management Area (CWMA) or Skagit Knotweed Working Group, completed extensive surveys of rivers and streams in the Upper Skagit watershed, treating knotweed in a top-down, prioritized approach along these waterways, and monitoring a large percentage of previously recorded knotweed patches in the Upper Skagit watershed. We continued using the prioritization strategy developed in 2009 to guide where work is completed. SFEG contracted with the Washington Conservation Corps (WCC) crew and rafting companies to survey, monitor and treat knotweed patches. In addition SFEG was assisted by the DNR Aquatics Puget Sound Corps Crew (PSCC) in knotweed survey and treatment. SFEG and WCC also received on-the-ground assistance in our efforts from several Skagit CWMA partners including: U.S. Forest Service, Seattle City Light and the Sauk-Suiattle Indian Tribe. The Sauk-Suiattle Indian Tribe received a grant from the EPA in 2011 to do survey and treatment work on the Lower Sauk River and in the town of Darrington through 2013. This work was done in coordination with SFEG’s Upper Skagit Knotweed Control Project. The knotweed program met its goal of surveying and treating both the upper mainstem floodplains of the Sauk and Skagit Rivers. SFEG and WCC surveyed for knotweed from May through June and then implemented treatment from July until the first week of September.
