Preliminary Geologic Map of the Mount Baker 30- by 60-Minute Quadrangle, Washington

The quadrangle is mostly rugged and remote and includes much of the North Cascade National Park and several dedicated Wilderness areas managed by the U.S. Forest Service. Geologic exploration has been slow and difficult. In 1858 George Gibbs (1874) ascended the Skagit River part way to begin the geographic and geologic exploration of the North Cascades. In 1901, Reginald Daly (1912) surveyed the 49th parallel along the Canadian side of the border, and George Smith and Frank Calkins (1904) surveyed the United States' side. Daly's exhaustive report was the first attempt to synthesize what has become an extremely complicated geologic story. -

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. -

WILLIAMS, Jr., and JANE G. FERRIGNO U.S. GEOLOGICAL SURVEY PROFESSIONAL PAPER 1386–K About 5 percent (about 75,000 km2) of Alaska is presently glacierized, including 11 mountain ranges, 1 large island, an island chain, and 1 archipelago. The total number of glaciers in Alaska is estimated at >100,000, including many active and former tidewater glaciers. Glaciers in every mountain range and island group are experiencing significant retreat, thinning, and (or) stagnation, especially those at lower elevations, a process that began by the middle of the 19th century. In southeastern Alaska and western Canada, 205 glaciers have a history of surging; in the same region, at least 53 present and 7 former large ice-dammed lakes have produced jökulhlaups (glacier-outburst floods). Ice-capped Alaska volcanoes also have the potential for jökulhlaups caused by subglacier volcanic and geothermal activity. Satellite remote sensing provides the only practical means of monitoring regional changes in glaciers in response to short- and long-term changes in the maritime and continental climates of Alaska. Geospatial analysis is used to define selected glaciological parameters in the eastern part of the Alaska Range. -
