Division of Mines and Mining
STATE OF WASHINGTON ARTHUR B. LANGLIE, GOVERNOR Department of Conservation and Development JOHN BROOKE FINK, Director THIRD BIENNIAL REPORT of the DIVISION OF MINES AND MINING For the Period Commencing January 1, 1939 and Ending January 1, 1941 By THOMAS B. HILL, SUPERVISOR J . w. MELROSE, GEOLOGIST OLYMPIA STATE PRI NTINC PLANT DIVISION OF MINES AND MINING Hon. John Brooke Fink, Director, Department of Conservation and Development, Olympia, Washington. Sir: I have the honor to submit herewith the third biennial report of the Division of Mines and Mining, covering the period from January l, 1939, to January 1, 1941. Respectfully, THOMAS B. HILL, Supervisor. DIVISION OF MINES AND MINING THOMAS B. HILL Supervisor SUMMARY OF MINERAL INFORMATION The present widespread interest in the mineral resources of Washington had its beginning in 1933 when the Director of the Department of Conserva tion and Devlopment devoted a substantial part of an allocation of $80,000 from Washington Emergency Relief Administration to mineral investigations. Two years later, the Division of Mines and Mining was created, and has continued the investigations, the work of compiling information and promoting the development of the mineral resources. Extensive information had been developed on the mineral resources of the State in the previous twenty-five years, largely through the Washington Geological Survey and the Division of Geology. This information had been published in some 50 or more bulletins and 1·eports, about half of which are now out of print. The information, while extensive, was scattered and in many instances fragmentary. The result of the work begun by the Department in 1933, and continued by this Division since 1935, is that now information is available on all the known mineral occurrences of the State. -

Meteorites, Asteroids, and Comets
Space Sci Rev (2018) 214:36 https://doi.org/10.1007/s11214-018-0474-9 Water Reservoirs in Small Planetary Bodies: Meteorites, Asteroids, and Comets Conel M.O’D. Alexander1 · Kevin D. McKeegan2 · Kathrin Altwegg3 Received: 10 January 2018 / Accepted: 11 January 2018 / Published online: 23 January 2018 © Springer Science+Business Media B.V., part of Springer Nature 2018 Abstract Asteroids and comets are the remnants of the swarm of planetesimals from which the planets ultimately formed, and they retain records of processes that operated prior to and during planet formation. They are also likely the sources of most of the water and other volatiles accreted by Earth. In this review, we discuss the nature and probable origins of asteroids and comets based on data from remote observations, in situ measurements by spacecraft, and laboratory analyses of meteorites derived from asteroids. The asteroidal par- ent bodies of meteorites formed ≤ 4 Ma after Solar System formation while there was still a gas disk present. It seems increasingly likely that the parent bodies of meteorites spectro- scopically linked with the E-, S-, M- and V-type asteroids formed sunward of Jupiter’s orbit, while those associated with C- and, possibly, D-type asteroids formed further out, beyond Jupiter but probably not beyond Saturn’s orbit. Comets formed further from the Sun than any of the meteorite parent bodies, and retain much higher abundances of interstellar mate- rial. CI and CM group meteorites are probably related to the most common C-type asteroids, and based on isotopic evidence they, rather than comets, are the most likely sources of the H and N accreted by the terrestrial planets. -

A review of studies of sexual dimorphism in the vertebrate fossil record revealed methods that were selected for use in ceratopsids. Mountain goats, bison, and pronghorn were selected as exemplar taxa for a proof of principle study that tested the selected methods, and informed and guided the investigation of sexual dimorphism in dinosaurs. Skulls of these exemplar taxa were measured in museum collections, and methods of analysing morphological variation were tested for their ability to demonstrate sexual dimorphism in their horns and horncores. -

An Examination of Ideology and Subject Formation Among Elite And
AN EXAMINATION OF IDEOLOGY AND SUBJECT FORMATION AMONG ELITE AND ORDINARY RESIDENTS IN THE BAKKEN SHALE, NORTH DAKOTA, 2015-2016 A Dissertation by THOMAS ANDREW LODER Submitted to the Office of Graduate and Professional Studies of Texas A&M University in partial fulfillment of the requirements for the degree of DOCTOR OF PHILOSOPHY Chair of Committee, Christian Brannstrom Committee Members, Forrest Fleischman Wendy Jepson Kathleen O’Reilly Head of Department, David Cairns August 2018 Major Subject: Geography Copyright 2018 Thomas Andrew Loder ABSTRACT The US shale energy boom of the late 2000s and 2010s has brought both economic growth and negative externalities to communities undergoing extraction. Building on previous research on fracking landscapes – as well as geographies of energy and natural resources and case studies of environmental subjectivity in extractive zones – this dissertation employed a suite of qualitative methods to examine the discourses and ideology used to support and oppose fracking-led development in North Dakota’s Bakken Shale. The dissertation consists of three substantive chapters. The first employs key actor interviews and participant observation to examine how pro-oil ideology is advanced by economic and political elites in North Dakota. This chapter concludes that elites frame support for oil as an extension of existing conservative ideologies prevalent in the state. The second substantive chapter consists of content analysis of coverage of oil- related events in state-level newspapers, specifically concentrating on a 2014 conservation ballot measure and the Keystone XL pipeline. This chapter concludes that pro-oil writers are more effective in their messaging due to focusing on economic and emotional appeals. -
Stable Isotopic Insights Into the Subsistence Patterns of Prehistoric Dogs (Canis Familiaris) and Their Human Counterparts in Northeastern North America
STABLE ISOTOPIC INSIGHTS INTO THE SUBSISTENCE PATTERNS OF PREHISTORIC DOGS (CANIS FAMILIARIS) AND THEIR HUMAN COUNTERPARTS IN NORTHEASTERN NORTH AMERICA A Dissertation Submitted to the Temple University Graduate Board in Partial Fulfillment of the Requirements for the Degree DOCTOR OF PHILOSOPHY by Sharon Allitt May 2011 Examining Committee Members: R. Michael Stewart, Advisory Chair, Temple University Anthony Ranere, Temple University Charles Weitz, Temple University Mark Schurr, Notre Dame University M. Anne Katzenberg, External Member, University of Calgary © Copyright 2011 by Sharon Allitt All Rights Reserved ! ii ABSTRACT Title: STABLE ISOTOPIC INSIGHTS INTO THE SUBSISTENCE PATTERNS OF PREHISTORIC DOGS (CANIS FAMILIARIS) AND THEIR HUMAN COUNTERPARTS IN NORTHEASTERN NORTH AMERICA Candidate's Name: Sharon Allitt Degree: Doctor of Philosophy Temple University, 2011 Doctoral Advisory Committee Chair: R. Michael Stewart, Phd There are four goals to this study. The first is to investigate the diet of prehistoric dogs (Canis familiaris) in the Northeast region of North America using stable isotope analysis. The second goal of this study is to generate independent data concerning the presence or absence of C4 resources, such as maize, in the diets of dogs. Third, this study investigates the use of dog bone as a proxy for human bone in studies assessing the presence of C4 resources at archaeological sites. The fourth goal of this study is to provide a check on existing interpretations of the material, macro- and micro- botanical records as it concerns the presence or absence of C4 resources at the sites involved in this study. Stable isotope analysis is a science that allows the measuring of the abundance ratio of two stable isotopes of a particular element.
