The absolute easternmost peak of the North Cascades is Chopaka Mountain, 7882 feet. An This probably is the most spectacular chunk abrupt and impressive 6700-foot scarp drops of alpine terrain owned by the state.

GEOLOGIC MAP of the CHELAN 30-MINUTE by 60-MINUTE QUADRANGLE, WASHINGTON by R
DEPARTMENT OF THE INTERIOR TO ACCOMPANY MAP I-1661 U.S. GEOLOGICAL SURVEY GEOLOGIC MAP OF THE CHELAN 30-MINUTE BY 60-MINUTE QUADRANGLE, WASHINGTON By R. W. Tabor, V. A. Frizzell, Jr., J. T. Whetten, R. B. Waitt, D. A. Swanson, G. R. Byerly, D. B. Booth, M. J. Hetherington, and R. E. Zartman INTRODUCTION Bedrock of the Chelan 1:100,000 quadrangle displays a long and varied geologic history (fig. 1). Pioneer geologic work in the quadrangle began with Bailey Willis (1887, 1903) and I. C. Russell (1893, 1900). A. C. Waters (1930, 1932, 1938) made the first definitive geologic studies in the area (fig. 2). He mapped and described the metamorphic rocks and the lavas of the Columbia River Basalt Group in the vicinity of Chelan as well as the arkoses within the Chiwaukum graben (fig. 1). B. M. Page (1939a, b) detailed much of the structure and petrology of the metamorphic and igneous rocks in the Chiwaukum Mountains, further described the arkoses, and, for the first time, defined the alpine glacial stages in the area. C. L. Willis (1950, 1953) was the first to recognize the Chiwaukum graben, one of the more significant structural features of the region. The pre-Tertiary schists and gneisses are continuous with rocks to the north included in the Skagit Metamorphic Suite of Misch (1966, p. 102-103). Peter Misch and his students established a framework of North Cascade metamorphic geology which underlies much of our construct, especially in the western part of the quadrangle. Our work began in 1975 and was essentially completed in 1980. -
Geologic Map of the North Cascade Range, Washington by Ralph A
Prepared in cooperation with Washington State Division of Geology and Earth Resources, U.S. National Park Service, and U.S. Forest Service Geologic Map of the North Cascade Range, Washington By Ralph A. Haugerud and Rowland W. Tabor Nontechnical pamphlet to accompany Scientific Investigations Map 2940 Looking south from the North Klawatti Glacier [Mbse]. In the right foreground, the glacier breaks into a heavily crevassed icefall where it descends steeply. Rock in the foreground knob is Eldorado Orthogneiss (unit TKgo), a 90 million-year-old stitching pluton, which here includes numerous dikes of light- colored pegmatite. Mount Buckner on the left skyline and Mount Forbidden hidden in clouds are also eroded from the Eldorado Orthogneiss (photographed in 1987). 2009 U.S. Department of the Interior U.S. Geological Survey CONTENTS Introduction.....................................................................................................................................................1 Using this report ....................................................................................................................................1 Map preparation ...................................................................................................................................1 Major sources of new data .................................................................................................................1 Acknowledgments ................................................................................................................................2 -

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. -
