Bill Reid Gallery Re-Opens ANd Commemorates 100Th Anniversary of One of Canada's Most Renowned Indigenous Artists In
FOR IMMEDIATE RELEASE June 9, 2020 Bill Reid Gallery Re-opens and Commemorates 100th Anniversary of One of Canada’s Most Renowned Indigenous Artists in – To Speak With a Golden Voice – Exhibition brings fresh perspective to Bill Reid’s legacy with rarely seen artworks and new commissions by Northwest Coast artists inspired by his life and practice VANCOUVER, BC — Bill Reid Gallery of Northwest Coast Art re-opens the gallery and celebrates the milestone centennial birthday of Bill Reid (1920–1998) with an exhibition about his extraordinary life and legacy, To Speak With a Golden Voice, from July 16, 2020 to April 11, 2021. Guest curated by Gwaai Edenshaw — considered to be Reid’s last apprentice — the group exhibition includes rarely seen treasures by Reid and works from artists such as Robert Davidson and Beau Dick. Tracing the iconic Haida artist’s lasting influence, two new artworks by contemporary artist Cori Savard (Haida) and singer-songwriter Kinnie Starr (Mohawk/Dutch/German//Irish) will be created for this highly anticipated exhibition. “Bill Reid was a master goldsmith, sculptor, community activist, and mentor whose lasting legacy and influence has been cemented by his fusion of Haida traditions with his own modernist aesthetic,” says Edenshaw. “Just about every Northwest Coast artist working today has a connection or link to Reid. Before he became renowned for his artwork, he was a CBC radio announcer recognized for his memorable voice — in fact, one of Reid’s many Haida names was Kihlguulins, or ‘golden voice.’ His role as a public figure helped him become a pivotal force in the resurgence of Northwest Coast art, introducing the world to its importance and empowering generations of artists.” Reid was born in Victoria, BC, to a Haida mother and an American father with Scottish-German roots. -
Limestone Resources of Western Washington
State of Washington DANIEL J. EVANS, Governor Department of Conservation H. MA URI CE AHLQUIST, Director DIVISION OF MINES AND GEOLOGY MARSHALL T. HUNTTING, Supervisor Bulletin No. 52 LIMESTONE RESOURCES OF WESTERN WASHINGTON By WILBERT R. DANNER With a section on the UME MOUNTAIN DEPOSIT By GERALD W. THORSEN STATII PRINTING PLANT, OLYMPI A, WASH, 1966 For sale by Department of Conservation, Olympia, Washington. Price, $4,50 FOREWORD Since the early days of Washington's statehood, limestone has been recognized as one of the important mineral resources _of the State. The second annual report of the Washington Geological Survey, published in 1903, gave details on the State's limestone deposits, and in later years five other reports published by the Survey and its successor agencies hove given additional information on this resource. Still other reports by Federal and private agencies hove been published in response to demands for data on limestone here. Although some of the earlier reports included analyses to show the purity of the rocks, very few of the samples for analysis were taken systemati cally in a way that would fairly represent the deposits sampled. Prior to 1900 limestone was produced for use as building stone here, and another important use was for the production of burned Ii me . Portland cement plants soon became leading consumers of Ii mestone, and they con tinue as such to the present time . Limestone is used in large quantities in the pulp industry in the Northwest, and in 1966 there was one commercial lime-burning plant in the State. Recognizing the potential for industrial development in Washington based on more intensive use of our mineral resources, and recognizing the need to up-dote the State's knowledge of raw material resources in order to channel those resources into the State's growing economy, the Industrial Row Materials Advisory Committee of the Deportment of Commerce and Economic Development in 1958 recommended that a comprehensive survey be made of the limestone resources of Washington. -

A Fine Day in Masset: Christopher Auchter Revisits Crucial Moment in Haida Renaissance
NOW IS THE TIME A Fine Day in Masset: Christopher Auchter Revisits Crucial Moment in Haida Renaissance By Philip Lewis August 13, 2019 It was a fine day in Masset: August 22, 1969. For the first time in living memory, a traditional totem pole was being raised in the community. Surrounded by their extended families, members of the Eagle and Raven Clans formed parallel teams to leverage the towering structure into place alongside the old church where it still stands to this day. A NATIONAL FILM BOARD OF CANADA PRODUCTION NOW IS THE TIME A NATIONAL FILM BOARD OF CANADA PRODUCTION NOW IS THE TIME Elders would speak of “a forest of totem poles,” recalling a time when the giant carvings were common throughout the Haida Gwaii archipelago, but by the late 1960s most had vanished — suppressed by Christian missionaries and assimilationist laws that aimed explicitly to eradicate Indigenous identity from the Canadian landscape. The new pole was the brainchild of Robert Davidson, also known by his Haida name, Guud San Glans, a visionary young artist who would reinvigorate the tradition, becoming a central figure in a vibrant Haida renaissance. While previous generations had kept Haida art alive with small-scale wooden and argillite carvings, Davidson was working a monumental scale that had not been seen in almost a century. Twenty-two-year-old Robert Davidson and his grandfather, Tsinii Robert. Hardly out of his teens at the time, Davidson and his project were the subject of a short NFB doc, released in 1970, called This Was the Time. But the film raised more questions than it answered, presenting events through the muddled lens of the dominant Euro-Canadian culture. -

Thiesse V i August 1988 11 MINES LIBRARY The thesis of Mark F. Thiesse is approved: 2H03 Thesis Advisor Department Chairman Dean, Graduate School University of Nevada Reno August 1988 iii ACKNOWLEDGEMENTS I would like to thank Dr. R .A. Schweickert for his help, encouragement and patience throughout this project. Dr. Bruce Wardlaw provided the conodont identification which suggested the Carboniferous (?) age of the metamorphic rocks. Other thanks go to Andy Markos and Bob Strobel for help with the thin sections and interesting discussions. And finally, thanks to Carol for typing and for funding this project. iv ABSTRACT The Fox Range in Northwestern Nevada is a typical Basin and Range fault block mountain range which has been tilted about 30° to the east, accelerating the erosion of Tertiary volcanic rocks along the steep western flanks, and exposing Paleozoic metamorphic rocks. The Paleozoic rocks consist of a very fine grained, siliceous mudstone which was regionally metamorphosed from mid-greenschist to mid-amphibolite facies producing argillite, schist, limestone, quartzite, and gneiss. These Paleozoic rocks exhibit three generations of structures. Di created the schistose and gneissic layering common throughout the range, along with abundant tight to isoclinal folds. D2 structures are dominated by two large, map-scale antiforms and occasional smaller, open to tight, east to northeast trending folds and assorted lineations. D3 structures are limited to a few north-south trending, open to gentle folds which affect all pre-Tertiary lithologies. -

Geology of the Canadian Rockies and Columbia Mountains Summary by Ben Gadd
Geology of the Canadian Rockies and Columbia Mountains Summary by Ben Gadd 1. Basic geological history of western Canada The evidence reposes in four great layers, each thousands of metres thick. These four great layers (I call them the ancient sediments, the old clastics, the middle carbonates and the young clastics) show two main phases in the geological history of western Canada. First came a long period of sediment deposition, followed by a shorter period of mountain-building. Throughout this time—1.7 billion years altogether—the movement of the world’s crustal plates played a key role. • See last page for the currently accepted geological time scale, with period names and dates. First phase: deposition of most of the rock. About 1.7 billion years ago, part of what is now North America was imbedded in a supercontinent (amalgamation of continents) called Columbia (no relation to the Columbia Mountains). The oldest sedimentary rock in the Rockies was deposited about this time in an inland sea on Columbia. This rock is mostly argillite—very hard mud—and it is now found at the northern end of the Rockies. It is not found in ranges west of the Rockies. The supercontinent of Columbia broke up about 200 million years later. While North America was drifting free some 1.5 billion years ago, a second batch of ancient argillite, with additional limestone and dolostone—more on dolostone in a minute—was deposited in another inland sea, this time at the southern end of the Canadian Rockies in the Waterton area, and to the west in what are now the Purcell Mountains, one of the ranges in the Columbia Mountains (Purcells, Selkirks, Monashees and Cariboos). -

Montana Bureau of Mines and Geology GEOLOGIC MAP OF THE MONTANA PART OF THE WALLACE 30' x 60' QUADRANGLE by Jeffrey D. Lonn and Mark D. McFaddan* Montana Bureau of Mines and Geology Open File Report MBMG 388 1999 This report has had preliminary reviews for conformity with Montana Bureau of Mines and Geology’s technical and editorial standards Partial support has been provided by the STATEMAP component of the National Cooperative Geologic Mapping Program of the U.S. Geological Survey under Contract Number 98-HQ-AG- 2080. *Geology Department, University of Idaho, Moscow, ID 83844 Figure 1. Age correlation of map units. 1 Introduction The Wallace 30' x 60' quadrangle contains structures critical to understanding the tectonic history of western Montana, but the area has been largely neglected by mapping geologists. In 1998, the joint U.S. Geological Survey/Montana Bureau of Mines and Geology STATEMAP project funded new mapping of the Montana portion of the Wallace quadrangle. Although Harrison et al. (1986) had compiled existing mapping (Calkins and Jones, 1912; Wallace and Hosterman, 1956; Campbell, 1960) and added some original mapping at the 1:250,000 scale, we remapped most of the area in an effort to unravel the structural complexities. Lewis et al. (1999) mapped the adjoining Idaho portion of the Wallace quadrangle. Unpublished mapping of some Revett Formation exposures by Appelgate and Lafco (1981) was invaluable in pointing the way towards some key areas. Additionally, structural geology has been well studied in the Coeur d’Alene mining district immediately to the west, and this knowledge has been instrumental in deciphering the geologic history of the Wallace quadrangle.
