The project is subject to the State Environmental Policy Act. SWCA carried out background research to identify previous cultural resources investigations and known archaeological sites within the project vicinity by reviewing historic maps and published historic, ethnographic, and environmental information. Background research indicates the project area has moderate to high potential for cultural resources to be present, and archaeological monitoring during construction is recommended.

SWCA Environmental Consultants (SWCA) was retained by EA Engineering, Science and Technology, Inc. to assess the probability for significant archaeological resources to be present on the parcel proposed for development, and to recommend potential measures for avoiding impacts to significant cultural resources. A building assessment was not included in this investigation. Project Location and Description The project is in the Denny Triangle area north of downtown Seattle Washington in Section 29 of Township 25 N, Range 4 East, Willamette Meridian (Figure 1). The project is on Parcel 066000‐2230, bounded by Denny Way on the north, Fairview Avenue N on the west, Boren Street on the southwest, Virginia Street on the southeast, and Minor Avenue on the northeast. The site comprises approximately 24,459 square feet and contains a two‐story office building that was constructed in 1937 (Figure 2). Regulatory Context The project is subject to the State Environmental Policy Act (SEPA), which requires project proponents to identify any places or objects on or adjacent to the project that are listed in, or eligible for, national, state, or local preservation registers, and to identify sites of archaeological, scientific, or cultural importance in or adjacent to the project. Project proponents are required to describe proposed measures to reduce or control impacts to those places, objects, and sites. The City of Seattle Department of Construction and Inspections (SDCI) prepared an environmental impact state (EIS) addendum to accompany the project through the City of Seattle’s Master Use Permit (MUP) process, and pursued a Determination of Significance (DS) for the project (SDCI 2017). In its review of the DS, the Washington State Department of Archaeology and Historic Preservation (DAHP) noted that nearby archaeological sites have been identified on similar landforms and requested that a cultural resources overview assessment for the parcel be conducted, and a report submitted to DAHP and interested Tribes. DAHP also requested that the existing 1937 building be recorded on a Washington State Historical Property Inventory (HPI) form. An “Appendix A” Report was completed for the building Mirro and Jaeger 2015), but submittal of an HPI form is not part of the scope of this overview. Other Washington state laws address archaeological sites and Native American burials. The Archaeological Sites and Resources Act (RCW 27.53) prohibits knowingly excavating or disturbing prehistoric and historic archaeological sites on public or private land. The Indian Graves and Records Act (RCW 27.44) prohibits knowingly destroying American Indian graves and provides that inadvertent disturbance through construction or other activities requires re‐interment under supervision of the appropriate Native American tribe. In order to prevent the looting or depredation of sites, any maps, records, or other information identifying the location of archaeological sites, historic sites, artifacts, or the site of traditional, ceremonial, or social uses and activities of Tribes are exempt from disclosure (RCW 42.56.300). The purpose of this report is to aid the project proponent in complying with these various legal requirements by assessing, based on background sources and field reconnaissance, the potential for encountering archaeological materials during construction. Recommendations are also included for any additional archaeological resources

WILLIS Isotopes, Inc., Westwood, New Jersey INTRODUCTION This list presents dates on samples measured at Isotopes, Inc., dur- ing the years 1963 to 1965 and measurements made previously for which sample data has been recently received. The many results which do not appear are withheld pending additional information or at the request of our clients. Procedures employed in sample pretreatment, preparation of CO2, and method of counting are generally unchanged, as are our methods of age calculation. Suitable bone samples are now pretreated by the method of Berger, Harney and Libby (1964). In May, 1965, the three counters and associated electronics previ- ously described (Isotopes I, II, III) were retired after producing well over 2000 radiocarbon dates, geophysical measurements, and ultralow- level C14 measurements. A completely new laboratory was activated em- ploying four new counters. Shielding consists of 31 cm of selected low- background steel, 10 cm paraffin and 2.5 cm "aged" lead. Each counter has its own multianode annular anticoincidence geiger counter. Elec- tronics were designed and fabricated at Isotopes, Inc. The counters have an active volume of 1 L and when operated at a normal pressure of 3 atm, yield background counts of slightly over 2 counts j min, Aox x 0.95 is ca. 18.7 at 24° C. C13/C12 ratios are measured periodically by our mass spectrometry section, but not routinely on samples unless requested by clients.

  • Pre-Vashon Interglacial Deposit Investigation
    Investigation of a Pre-Vashon Interglacial Fine-Grained Organic-Rich Sedimentary Deposit, South Lake Union, Seattle, Washington Cody Gibson A report prepared in partial fulfillment of the requirements for the degree of Master of Science Earth and Space Sciences: Applied Geosciences University of Washington March 2017 Project Mentors: Kathy Troost, University of Washington Matt Smith, GeoEngineers Inc. Internship Coordinator: Kathy Troost Reading Committee: Kathy Troost Juliet Crider MESSAGe Technical Report Number: 56 ©Copyright Cody Gibson i Executive Summary This study evaluates a fine-grained interglacial deposit found in the subsurface of the South Lake Union (SLU) area, Seattle, Washington. The nearly one-square-km SLU study area is defined as north of Denny Way, south of Aloha Street, east of Aurora Avenue, and west of Interstate 5. The evaluation required an in-depth study of over 600 existing geotechnical and environmental boring logs found for the study area. My evaluation consisted of mapping the distribution, determining the depositional environment, and characterizing the organic-rich pre-Vashon deposits. The fine-grained organic-rich deposits correlate to the Olympia formation, which occurred prior to the last glaciation of the Puget Sound Lowland known as the Vashon. To characterize the subsurface conditions in SLU, I assigned the materials described on the boring logs to one of 3 basic layers: pre-Vashon, Olympia Formation (Qob), and Vashon. In the SLU, the Qob consists of grey silt with interbeds of sand and gravel, and has an abundance of organic debris including woody debris such as well-preserved logs and branches, fresh-water diatoms, and fresh-water aquatic deposits such as peat.

  • The Manis Mastodon Site
    The Manis Mastodon Site Raven Taylor Division - Junior History Paper Word Count - 1562 Since I was little, I’ve wanted to help animals. Naturally, for me as a five-year-old, my dream job was to become a vet. There was something about helping more than just the dogs and cats, so my enthusiasm for becoming a vet turned into my enthusiasm of becoming a zoologist. Around age 9, I met a lady named Iesha while my mom and I were on our way to Arizona. We started talking and then Iesha told us she had just been Hawaii helping leatherback turtles. The stranger sitting next to me quickly became the coolest person I had ever met. She went on to explain that she was going to Arizona to help the bats at a festival so they wouldn’t go extinct from a fungus. All I knew at that point was that I wanted to do what she did. She got to travel the world and save animals, and I thought that was really fantastic. So, yet again, my dream job changed to becoming a zoologist that traveled around the world and saved endangered species. Due to a recent assignment, I’ve found that the job I truly want to do, and that is under the label of Endangered Species Biologist. Since then my heart has been set on saving African Elephants from going extinct. Oddly enough, one of the topics to do for my project was to write about the mastodon, which is an animal that has gone extinct.

    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.

  • Manis Mastodon Collection: an Exciting Donation to the Washington State Historical Society
    FOR IMMEDIATE RELEASE: June 12, 2019 MEDIA CONTACT: Julianna Verboort, Marketing and Communications Director, Washington State Historical Society, 253-798-5902 or [email protected] Manis Mastodon Collection: An exciting donation to the Washington State Historical Society Tacoma, WA – Imagine standing beside a mucky pit in your yard on the Olympic Peninsula and hearing “This is the most important archaeological discovery in the world today.” Those words were spoken by Washington State University professor and researcher Dr. Richard Daugherty to Clare and Emanuel Manis on a sweltering Sequim afternoon more than 40 years ago. A dig on their property turned up the remains of an ancient mastodon, and some major surprises, leading to a re-write of North American history. Recently, Clare Manis Hatler decided to donate the collection of over 50 cartons including bones, ivory, teeth, soil samples, stone tools, photographs, field notes, educational materials and more, to the Washington State Historical Society. "I dedicate this gift to two great men,” Hatler remarked. “This gift would not have happened without Emanuel Manis, who made the effort to share the site with the public. He wanted everyone to participate in and learn about the wonderful discoveries made daily during the dig. Secondly, to Dr. Carl E. Gustafson, a dedicated professional, investing over 30 years of his life into revealing the site’s mysteries, without expectation of accolades or financial gain. Both men are gone now, Emanuel in 2000 and Carl in 2016, but never to be forgotten.” “We are thrilled to receive the Manis mastodon collection as a donation from Clare Manis Hatler.
