INTRODUCTION This report provides an overview of the key patterns that emerged from the spatial analyses of the destination and route data collected during the 2013 Sustainable Roads workshops on the Mount Baker Snoqualmie (MBS) National Forest. We excluded the pilot workshop data from the analyses because a somewhat different process was used to collect the mapped data. The data used in the analysis was collected from 262 participants in eight workshops (Bellingham, Sedro-Woolley, Darrington, Monroe, Everett, Seattle, Issaquah, Enumclaw). During the workshops, participants mapped up to eight destinations of importance to them, and in most cases, also mapped the routes they took to each destination. For each destination and its associated route, participants also provided the following information. Name of the place Why the destination is especially important What activities or work the participant does there How often the participant visits the place in a typical year What type of transportation the participant uses to get there Of the 262 participants, 252 provided useable data for destinations and 246 provided useable data for roads. The dataset used in the spatial analysis contained 1733 records for destinations and 1609 records for roads. We entered the worksheet data for the destination and road mapping exercise into an Excel spreadsheet. The activities associated with each destination were grouped into eight categories (camping/relaxation, collecting/harvesting, hiking, motorized recreation, observation, sociocultural, strenuous recreation, and winter recreation). Although most people listed no more than two activities for a location, some people listed up to six different activities for certain destinations. The description of why a participant visited a particular location was similarly classified as a set of eight different values. Given the way the question was

    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.

  • Winter Summits
    EVERETT MOUNTAINEERS Recommended Winter Summits Snow and weather conditions greatly influence the difficulty of winter scrambles. Because conditions change very quickly, things like road access, avalanche hazard, strenuousness, and summit success can vary a tremendous amount. So these ratings are only a rough comparison of the peaks. Winter scrambling can be a dangerous activity. Be a smart scrambler -- be willing to turn back if conditions are unsafe. Even a slight deviation from the surveyed routes may affect exposure and avalanche hazard considerably. The fact that a peak is listed here does not represent that it will be safe. Exposure Rating Avalanche Rating A: Falling will only get snow on your face. B: Falling may require self arrest, but usually good A: Usually safe in high, considerable, moderate, and low run-out. avalanche conditions. C: Falling requires self arrest, unchecked falls could B: Often safe in moderate and low conditions. be serious. C: Only recommended in low conditions.
