Photographs should be black and white glossy prints, 5x7, with caption and photographer's name on back. Manuscripts should be typed double-spaced and include writer's name, address and phone number. foreword Since the North Cascades National Park was indubi­ tably the event of this past year, this issue of The Mountaineer attempts to record aspects of that event. Many other magazines and groups have celebrated by now, of course, but hopefully we have managed to avoid total redundancy. Probably there will be few outward signs of the new management in the park this summer. A great deal of thinking and planning is in progress as the Park Serv­ ice shapes its policies and plans developments. The North Cross-State highway, while accessible by four­ wheel vehicle, is by no means fully open to the public yet. So, visitors and hikers are unlikely to "see" the changeover to park status right away. But the first articles in this annual reveal both the thinking and work which led to the park, and the think­ ing which must now be done about how the park is to be used.

    1 2 3 4 NOTE : THIS IS A DIGITAL TRANSCRIPTION OF THE ORIGINAL INDEX . The original document was scanned page by page. The results, beginning with this page, were then processed using optical character recognition (OCR) software, edited for accuracy and reformatted in MS Word. A marker is placed beneath the record that ends each page of the original. - Tom Cushing, Mountaineers History Committee, March, 2009 HOW TO USE THE INDEX This index to the Mountaineer Annual is divided into two parts: the Subject Index and the Proper Names Index (PNI). To use this index, find the year of publication of the Annual in dark type followed by a colon and the page number of the citation. Example: Ansell, Julian, 73: 80 (c/n) This means that a climbing note by Julian Ansell can be found on page 80 in the Annual published in 1973. Unnumbered pages are designated by letter and number of the last preceding page: 16, 16A, 16B. WHAT IS IN THE INDEX? The PNI contains all proper names of persons, organizations and places. If names are identical, persons precede places. Included as persons are all authors of articles, poems, and books reviewed, all artists, photographers and cartographers, as well as persons of note written about in the annuals. Authors of climbing notes are indexed. Authors of outing notes, obituaries, and book reviews are not. Maiden and married names, and alternative first and second names are listed as published, with cross-references where known. Included as places in the PNI are all geographical locations and special properties, such as huts or lodges.

  • The Cascades
    The Cascades The Cascade Mountain Range is about 700 miles long, extending from southwestern British Columbia, Canada south through Washington and Oregon, into north-central California (see map). This mountain chain consists of a series of volcanoes and innumerable smaller vents and cones located about 80 to 150 miles inland from the Pacific Ocean. Four (4) national parks are situated within the Cascades, including North Cascades National Park in north-central Washington, Mount Rainier in west- central Washington, Crater Lake in south-central Oregon, and Lassen National Park, centered on Mount Lassen, the southern-most Cascade peak, situated in north- central California. Figure 1 – Cascade Range Many peaks exceed 10,000 feet (3,000 m), including Mount Hood (11,235 feet [3,424 m], highest point in Oregon) and Mount Rainier (14,410 feet [4,392 m], highest in Washington and in the Cascade Range). Most of the summits are extinct volcanoes, but Lassen Peak (10,457 feet [3,187 m]) and several others have erupted in the recent past. Mount Baker (10,778 feet [3,285 m]) steamed heavily in 1975, and Mount St. Helens (8,365 feet [2,550 m]) erupted in 1980 and again in 1981. Page 1 of 11 The modern-day definition of the extent of the Cascades is generally accepted to mean a volcano between the end members (Mount Lassen to the south and Mount Meager to the north). There is also some discussion as to whether “Three Sisters”, near the center of the range is really 1 vent or 3 volcanoes very close to one another.

  • Hydrology and Geomorphic Evolution of Basaltic Landscapes, High Cascades, Oregon
    AN ABSTRACT OF THE DISSERTATION OF Anne Jefferson for the degree of Doctor of Philosophy in Geology presented on September 20, 2006. Title: Hydrology and Geomorphic Evolution of Basaltic Landscapes, High Cascades, Oregon Abstract approved: ____________________________________________________________ Gordon E. Grant Stephen T. Lancaster The basaltic landscapes of the Oregon High Cascades form a natural laboratory for examining how geologic setting and history influence groundwater flowpaths, streamflow sensitivity to climate, and landscape evolution. In the High Cascades, highly permeable young basaltic lavas form extensive aquifers. These aquifers are the dominant sources of summer streamflow for the Willamette River and its tributary, the McKenzie River, whose watershed forms the study area. Groundwater is discharged at large volume, cold springs, and discharge, temperature, and isotopic measurements at seven springs were used to constrain groundwater patterns. Lava flow geometries have a significant influence on groundwater recharge areas and flowpaths, sometimes superseding topographic controls. Transit times to springs are ~3-14 years, and flowpaths are generally shallow and have limited contact with deeper geothermal systems, except at fault zones. Time-series analyses of historical discharge, precipitation, snow, and temperature records reveal that the distribution of permeable rocks and resultant groundwater systems strongly influence streamflow response to climatic forcing. The annual hydrograph is shaped by groundwater storage and release, but inter-annual streamflow variability is largely the result of climatic forcing. Over the past 60 years, warmer winters and earlier snowmelt have lengthened the summer recession period and decreased autumn minimum discharges in a groundwater- dominated watershed. A chronosequence of dated rock units, combined with field observations and measurements of slopes, contributing areas, and drainage densities, shows that the geologic history of a watershed controls the stage of drainage development.
