FOREWORD Most travelers who have driven through eastern Washington have seen a geologic and scenic feature that is unique-nothing like it is to be found anywhere else in the world. This is the Channeled Scab­ land, a gigantic series of deeply cut channels in the erosion-resistant Columbia River basalt, the rock that covers most of the east-central and southeastern part of the state. Grand Coulee, with its spectac­ ular Dry Falls, is one of the most widely known features of this ex­ tensive set of dry channels. Many thousands of travelers must have wondered how this Chan­ neled Scabland came into being, and many geologists also have speculated as to its origin. Several geologists have published papers outlining their theories of the scabland's origin, but the geologist who has made the most thorough study of the problem and has ex­ amined the whole area and all the evidence having a bearing on the problem is Dr. J Harlen Bretz.

The Department is required to submit an annual report (per RCW 77.12.820) summarizing the Department’s eastern Washington pheasant activities under the program. Pheasant harvest has declined in Eastern Washington over the past two decades. To address hunting success rates and pheasant habitat loss, the Department created the EWPEP. The EWPEP completes habitat enhancement to benefit wild pheasant populations and targets the decline by releasing adult rooster pheasants on public lands. The Washington State Legislature funded the EWPEP in 1997 with a dedicated account called the Eastern Washington Pheasant Enhancement account. The funding is derived from a portion of small game hunting licenses, based on the proportion of purchasers who hunt pheasants in eastern Washington.

    COLONIZER GEOARCHAEOLOGY OF THE PACIFIC NORTHWEST REGION A Dissertation DR. BRETT R. LENZ COLONIZER GEOARCHAEOLOGY OF THE PACIFIC NORTHWEST REGION, NORTH AMERICA Thesis submitted for the degree of Doctor of Philosophy at the University of Leicester By Brett Reinhold Lenz Department of Archaeology and Ancient History University of Leicester June 2011 1 DEDICATION This work is dedicated to Garreck, Haydn and Carver. And to Hank, for teaching me how rivers form. 2 Abstract This dissertation involves the development of a geologic framework applied to upper Pleistocene and earliest Holocene archaeological site discovery. It is argued that efforts to identify colonizer archaeological sites require knowledge of geologic processes, Quaternary stratigraphic detail and an understanding of basic soil science principles. An overview of Quaternary geologic deposits based on previous work in the region is presented. This is augmented by original research which presents a new, proposed regional pedostratigraphic framework, a new source of lithic raw material, the Beezley chalcedony, and details of a new cache of lithic tools with Paleoindian affinities made from this previously undescribed stone source. 3 ACKNOWLEDGEMENTS The list of people who deserve my thanks and appreciation is large. First, to my parents and family, I give the greatest thanks for providing encouragement and support across many years. Without your steady support it would not be possible. Thanks Mom and Dad, Steph, Jen and Mellissa. To Dani and my sons, I appreciate your patience and support and for your love and encouragement that is always there. Due to a variety of factors, but mostly my own foibles, the research leading to this dissertation has taken place over a protracted period of time, and as a result, different stages of my personal development are likely reflected in it.

Both the No Action and Action Alternatives include four potential operational scenarios that could occur annually within their respective ranges, depending upon the hydrology of any given year. Both alternatives include refilling the reservoir to elevation 1570 feet by September 22. The No Action Alternative is the preferred alternative. The draft environmental impact statement provided Reclamation’s determination that the Action Alternative “may affect but is not likely to adversely affect” the federally listed bald eagle (Haliaeetus leucocephalus) and would have no effect on the federally listed pygmy rabbit (Brachylagus idahoensis) or Ute ladies’-tresses (Spiranthes diluvialis).
