Cobb of the U.S. Geological Survey main- tained a truly exceptional database on the geology and mineral deposits of Alaska—manifested in hundreds of published mineral locality maps, bibliogra- phies, and compilations of Alaska references. His work anticipated a fundamen- tal need to define the mineral endowment of Alaska during the long process that culminated in the Alaska National Interest Lands Conservation Act of 1981 (ANILCA). Almost 20 years later, Ed Cobb’s maps, bibliographies, and publica- tions, outdated as they have become in some ways, remain a mainstay of Alaska geology, land planning, and mineral exploration. Geology is a cumulative science built on the work of our predecessors. No one produced a better regional geologic information database for others to build on than did Ed Cobb in Alaska. -

Environmental and Cultural Overview of the Yukon Flats Region Prepared By: Kevin Bailey, USFWS Archaeologist Date: 2/12/2015 In
Environmental and Cultural Overview of the Yukon Flats Region Prepared by: Kevin Bailey, USFWS Archaeologist Date: 2/12/2015 Introduction With a substantial population of Native people residing in their traditional homeland and living a modern traditional lifestyle, the Yukon Flats Refuge and all of the Alaskan Interior is a dynamic and living cultural landscape. The land, people, and wildlife form a tight, interrelated web of relationships extending thousands of years into the past. Natural features and human created “sites” form a landscape of meaning to the modern residents. The places and their meanings are highly relevant to modern residents, not just for people and culture but for the land. To many Gwich’in people culture is not distinct from their homeland. Although only minimally discussed in this overview, this dynamic living cultural landscape should be considered and discussed when writing about this area. Environmental Setting Containing the largest interior basin in Alaska, the Yukon Flats Refuge encompasses over 11 million acres of land in east central Alaska. Extending roughly 220 miles east-west along the Arctic Circle, the refuge lies between the Brooks Range to the north, and the White-Crazy Mountains to the south. The pipeline corridor runs along the refuge’s western boundary while the eastern boundary extends within 30 miles of the Canadian border. The Yukon River bisects the refuge, creating the dominant terrain. As many as 40,000 lakes, ponds, and streams may occur on the refuge, most concentrated in the flood plain along the Yukon and other rivers. Upland terrain, where lakes are less abundant, is the source of important drainage systems. -

RSL fell below its present level around 13,900 cal yr BP, suggesting regional deglaciation was complete by then. RSL stayed at least several meters below modern levels until the mid-Holocene, when it began a fluctuating rise that probably tracked isostatic depression and rebound caused by varying ice loads in nearby Glacier Bay. -

(Photo by Gil Mull) i FOREWORD In keeping with the tradition of previous issues of Short Notes on Alaska Geology, this issue offers articles on a range of geologic topics in Alaska as diverse as the authors who prepared them. By my brief read, the articles cover the fields of geochemistry, geochronology, mineralogy, petrology, petrography, structural geology, stratigraphy, sedimentology, and paleontology. The authors represent the Alaska Division of Geological & Geophysical Surveys (DGGS), University of Alaska Fairbanks, U.S. Geological Survey, and numerous other universities and private companies in the U.S., Canada, Ireland, and even Czech Republic. We greatly appreciate their efforts in this significant contribution toward STATE OF ALASKA advancing the knowledge of Alaska’s geology. Frank H. Murkowski, Governor DEPARTMENT OF NATURAL RESOURCES Assembling and publishing a high-quality collection of peer- Tom Irwin, Commissioner reviewed articles such as this require significant dedication of time and effort over a period of at least a year and a half.
