Emplacement of a Silicic Lava Dome Through a Crater Glacier: Mount St Helens, 2004–06
14 Annals of Glaciology 45 2007 Emplacement of a silicic lava dome through a crater glacier: Mount St Helens, 2004–06 Joseph S. WALDER, Richard G. LaHUSEN, James W. VALLANCE, Steve P. SCHILLING United States Geological Survey, Cascades Volcano Observatory, 1300 Southeast Cardinal Court, Vancouver, Washington WA 98683-9589, USA E-mail: [email protected] ABSTRACT. The process of lava-dome emplacement through a glacier was observed for the first time after Mount St Helens reawakened in September 2004. The glacier that had grown in the crater since the cataclysmic 1980 eruption was split in two by the new lava dome. The two parts of the glacier were successively squeezed against the crater wall. Photography, photogrammetry and geodetic measure- ments document glacier deformation of an extreme variety, with strain rates of extraordinary magnitude as compared to normal alpine glaciers. Unlike normal temperate glaciers, the crater glacier shows no evidence of either speed-up at the beginning of the ablation season or diurnal speed fluctuations during the ablation season. Thus there is evidently no slip of the glacier over its bed. The most reasonable explanation for this anomaly is that meltwater penetrating the glacier is captured by a thick layer of coarse rubble at the bed and then enters the volcano’s groundwater system rather than flowing through a drainage network along the bed. INTRODUCTION ice bodies have been successively squeezed between the Since October 2004, a lava dome has been emplaced first growing lava dome and the crater walls. through, and then alongside, glacier ice in the crater of Several examples of lava-dome emplacement into ice Mount St Helens, Washington state, US. -
USGS Geologic Investigations Series I-1963, Pamphlet
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. -

Alaska Range
Alaska Range Introduction The heavily glacierized Alaska Range consists of a number of adjacent and discrete mountain ranges that extend in an arc more than 750 km long (figs. 1, 381). From east to west, named ranges include the Nutzotin, Mentas- ta, Amphitheater, Clearwater, Tokosha, Kichatna, Teocalli, Tordrillo, Terra Cotta, and Revelation Mountains. This arcuate mountain massif spans the area from the White River, just east of the Canadian Border, to Merrill Pass on the western side of Cook Inlet southwest of Anchorage.
