    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.

  • Terrestrial Mollusks of Attu, Aleutian Islands, Alaska BARRY ROTH’ and DAVID R
    ARCTK: VOL. 34, NO. 1 (MARCH 1981), P. 43-47 Terrestrial Mollusks of Attu, Aleutian Islands, Alaska BARRY ROTH’ and DAVID R. LINDBERG’ ABSTRACT. Seven species of land mollusk (2 slugs, 5 snails) were collected on Attu in July 1979. Three are circumboreal species, two are amphi-arctic (Palearctic and Nearctic but not circumboreal), and two are Nearctic. Barring chance survival of mollusks in local refugia, the fauna was assembled overwater since deglaciation, perhaps within the last 10 OOO years. Mollusk faunas from Kamchatka to southeastern Alaska all have a Holarctic component. A Palearctic component present on Kamchatka and the Commander Islands is absent from the Aleutians, which have a Nearctic component that diminishes westward. This pattern is similar to that of other soil-dwelling invertebrate groups. RESUM& Sept espbces de mollusques terrestres (2 limaces et 5 escargots) furent prklevkes sur I’ile d’Attu en juillet 1979.

Open-file report 75-150 1975 This report is preliminary and has not been edited or reviewed for conformity with Geological Survey standards AGE AND TECTONIC SIGNIFICANCE OF VOLCANIC ROCKS ON ST. MATTHEW ISLAND, BERING SEA, ALASKA By WILLIAM W. PATTON, JR., MARVIN A. LANPHERE, THOMAS P. MILLER, and RICHARD A. SCOTT Menlo Park, Calif., Anchorage, Alaska, Denver, Colo. Abstract.-- 'Reconnaissance investigations of the heretofore little known volcanic assemblage on St. Matthew Island provide significant information on the tectonic history of the Bering Sea shelf. St. Matfhew Island is made up of approximately 500 m of subaerial calc-alkaline volcanic rocks ranging in composition from high-alumina basalt to rhyolite. Four K-Ar analyses of samples from this volcanic sequence give Late Cretaceous ages of 65-77 m.y., and intercalated carbonaceous tuff layers yield Cretaceous pollen assemblages. Along the northeast coast of St. Matthew Island the volcanic rocks are intruded by granodiorite that gives an early Tertiary K-Ar age of 61 m.y. Correlations with on-land geology in northeast Siberia and marine geophysical data from the western Bering Sea strongly suggest that St. Matthew Island represents a southeastward extension of the Okhotsk- Chukotsk belt, a Late Cretaceous and early Tertiary volcanic arc that borders the Pacific margin of Siberia for 3,000 km.

Houghton, Chairperson Helge M. Gonnermann Christina Neal Thomas Shea John Allen © 2017, Samantha Jo Isgett ii Acknowledgements I probably would not be “standing here today” if my advisor Bruce Houghton had not introduced me to the wonderful world of volcanology. I entered his 300 level volcanology class as a naïve sophomore who had no ambitions of going to graduate school and left knowing that I wanted to be volcanologist and the steps that I needed to take to get there. Bruce has a passion not only for solving the big science question, but also in passing on his knowledge and skill-sets to his students. I cannot thank Bruce enough for seeing in me the potential makings of a scientist and guiding me there. It was, and always will be, a privilege to work with you. I would like to thank my committee — Helge Gonnermann, Thomas Shea, Christina Neal, and John Allen — for pushing me to take every problem and interpretation just a little (or a lot) further. I am especially grateful to Tom and John for stepping in at the last hour. Thank you all for your time and patience. Alain Burgisser, Laurent Arbaret, and Sarah Fagents also brought outside perspectives and skill-sets that were crucial for this project.
