  • 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).

  • Wilderness Visitors and Recreation Impacts: Baseline Data Available for Twentieth Century Conditions
    United States Department of Agriculture Wilderness Visitors and Forest Service Recreation Impacts: Baseline Rocky Mountain Research Station Data Available for Twentieth General Technical Report RMRS-GTR-117 Century Conditions September 2003 David N. Cole Vita Wright Abstract __________________________________________ Cole, David N.; Wright, Vita. 2003. Wilderness visitors and recreation impacts: baseline data available for twentieth century conditions. Gen. Tech. Rep. RMRS-GTR-117. Ogden, UT: U.S. Department of Agriculture, Forest Service, Rocky Mountain Research Station. 52 p. This report provides an assessment and compilation of recreation-related monitoring data sources across the National Wilderness Preservation System (NWPS). Telephone interviews with managers of all units of the NWPS and a literature search were conducted to locate studies that provide campsite impact data, trail impact data, and information about visitor characteristics. Of the 628 wildernesses that comprised the NWPS in January 2000, 51 percent had baseline campsite data, 9 percent had trail condition data and 24 percent had data on visitor characteristics. Wildernesses managed by the Forest Service and National Park Service were much more likely to have data than wildernesses managed by the Bureau of Land Management and Fish and Wildlife Service. Both unpublished data collected by the management agencies and data published in reports are included. Extensive appendices provide detailed information about available data for every study that we located. These have been organized by wilderness so that it is easy to locate all the information available for each wilderness in the NWPS. Keywords: campsite condition, monitoring, National Wilderness Preservation System, trail condition, visitor characteristics The Authors _______________________________________ David N.

Box 156 Un ? ve rs i ty Stat i on Seattle, './n. 98 105 SCRIPT FOR NORTH CASCAOES SLIDE SHOW (75 SI Ides) I ntroduct Ion : The North Cascades fiountatn Range In the State of VJashington Is a great tangled chain of knotted peaks and spires, glaciers and rivers, lakes, forests, and meadov;s, stretching for a 150 miles - roughly from Pt. fiainier National Park north to the Canadian Border, The h undreds of sharp spiring mountain peaks, many of them still unnamed and relatively unexplored, rise from near sea level elevations to seven to ten thousand feet. On the flanks of the mountains are 519 glaciers, in 9 3 square mites of ice - three times as much living ice as in all the rest of the forty-eight states put together. The great river valleys contain the last remnants of the magnificent Pacific Northwest Rain Forest of immense Douglas Fir, cedar, and hemlock. f'oss and ferns carpet the forest floor, and wild• life abounds. The great rivers and thousands of streams and lakes run clear and pure still; the nine thousand foot deep trencli contain• ing 55 mile long Lake Chelan is one of tiie deepest canyons in the world, from lake bottom to mountain top, in 1937 Park Service Study Report declared that the North Cascades, if created into a National Park, would "outrank in scenic quality any existing National Park in the United States and any possibility for such a park." The seven iiiitlion acre area of the North Cascades is almost entirely Fedo rally owned, and managed by the United States Forest Service, an agency of the Department of Agriculture, The Forest Ser• vice operates under the policy of "multiple use", which permits log• ging, mining, grazing, hunting, wt Iderness, and alI forms of recrea• tional use, Hov/e ve r , the 1937 Park Study Report rec ornmen d ed the creation of a three million acre Ice Peaks National Park ombracing all of the great volcanos of the North Cascades and most of the rest of the superlative scenery.

  • The Wild Cascades
    THE WILD CASCADES Fall, 1984 2 The Wild Cascades PRESIDENT'S MESSAGE ONCE THE LINES ARE DRAWN, THE BATTLE IS NOT OVER The North Cascades Conservation Council has developed a reputation for consistent, hard-hitting, responsible action to protect wildland resources in the Washington Cascades. It is perhaps best known for leading the fight to preserve and protect the North Cascades in the North Cascades National Park, the Pasayten and Glacier Peak Wilderness Areas, and the Ross Lake and Lake Chelan National Recreation Areas. Despite the recent passage of the Washington Wilderness Act, many areas which deserve and require wilderness designation remain unprotected. One of the goals of the N3C must be to assure protection for these areas. In this issue of the Wild Cascades we have analyzed the Washington Wilderness Act to see what we won and what still hangs in the balance (page ). The N3C will continue to fight to establish new wilderness areas, but there is also a new challenge. Our expertise is increasingly being sought by government agencies to assist in developing appropriate management plans and to support them against attempts to undermine such plans. The invitation to participate more fully in management activities will require considerable effort, but it represents a challenge and an opportunity that cannot be ignored. If we are to meet this challenge we will need members who are either knowledgable or willing to learn about an issue and to guide the Board in its actions. The Spring issue of the Wild Cascades carried a center section with two requests: 1) volunteers to assist and guide the organization on various issues; and 2) payment of dues.

  • WDFW Washington State Recovery Plan for the Lynx
    STATE OF WASHINGTON March 2001 LynxLynx RecoveryRecovery PlanPlan by Derek Stinson Washington Department of FISH AND WILDLIFE Wildlife Program Wildlife Diversity Division WDFW 735 In 1990, the Washington Fish and Wildlife Commission adopted procedures for listing and delisting species as endangered, threatened, or sensitive and for writing recovery and management plans for listed species (WAC 232-12-297, Appendix C). The lynx was classified by the Washington Fish and Wildlife Commission as a threatened species in 1993 (Washington Administrative Code 232-12-011). The procedures, developed by a group of citizens, interest groups, and state and federal agencies, require that recovery plans be developed for species listed as threatened or endangered. Recovery, as defined by the U.S. Fish and Wildlife Service, is “the process by which the decline of an endangered or threatened species is arrested or reversed, and threats to its survival are neutralized, so that its long-term survival in nature can be ensured.” This document summarizes the historic and current distribution and abundance of the lynx in Washington, describes factors affecting the population and its habitat, and prescribes strategies to recover the species in Washington. The draft state recovery plan for the lynx was reviewed by researchers and state and federal agencies. This review was followed by a 90 day public comment period. All comments received were considered in preparation of this final recovery plan. For additional information about lynx or other state listed species, contact: Manager, Endangered Species Section Washington Department of Fish and Wildlife 600 Capitol Way N Olympia WA 98501-1091 This report should be cited as: Stinson, D.

  • Geology of the Northern Part of the Southeast Three Sisters
    AN ABSTRACT OF THE THESIS OF Karl C. Wozniak for the degree of Master of Science the Department cf Geology presented on February 8, 1982 Title: Geology of the Northern Part of the Southeast Three Sisters Quadrangle, Oregon Redacted for Privacy Abstract approved: E. M. Taylorc--_, The northern part of the Southeast Three Sisters quadrangle strad- dles the crest of the central High Cascades of Oregon. The area is covered by Pleistocene and Holocene volcanic and volcaniclastic rocks that were extruded from a number of composite cones, shield volcanoes, and cinder cones. The principal eruptive centers include Sphinx Butte, The Wife, The Husband, and South Sister volcanoes. Sphinx Butte, The Wife, and The Husband are typical High Cascade shield and composite vol- canoes whose compositions are limited to basalt and basaltic andesite. South Sister is a complex composite volcano composed of a diverse assem- blage of rocks. In contrast with earlier studies, the present investi- gation finds that South Sister is not a simple accumulation of andesite and dacite lavas; nor does the eruptive sequence display obvious evolu- tionary trends or late stage divergence to basalt and rhyolite. Rather, the field relations indicate that magmas of diverse composition have been extruded from South Sister vents throughout the lifespan of this volcano. The compositional variation at South Sister is. atypical of the Oregon High Cascade platform. This variation, however, represents part of a continued pattern of late Pliocene and Pleistocene magmatic diver- sity in a local region that includes Middle Sister, South Sister, and Broken Top volcanoes. Regional and local geologic constraints combined with chemical and petrographic criteria indicate that a local subcrustal process probably produced the magmas extruded fromSouth Sister, whereas a regional subcrustal process probably producedthe magmas extruded from Sphinx Butte, The Wife, and The Husband.
