  • Luckiamute Meadows Property Funding
    DOE F 1325.8 e Electronic Form Approved by CGIR - 01/20/95 (8-89) United States Government Department of Energy Bonneville Power Administration memorandum DATE: May 15, 2013 REPLY TO ATTN OF: KEC-4 SUBJECT: Environmental Clearance Memorandum TO : Dorie Welch Project Manager – KEWM-4 Proposed Action: Luckiamute Meadows property funding. Fish and Wildlife Project No.: 2011-003-00, Contract # BPA-007071 Categorical Exclusion Applied (from Subpart D, 10 C.F.R. Part 1021): B1.25 Real Property transfers for cultural protection, habitat preservation and wildlife management. Location: Kings Valley quadrangle, in Benton County, Oregon (near Kings Valley, Oregon) Proposed by: Bonneville Power Administration (BPA) Description of the Proposed Action: The BPA is proposing to fund the Greenbelt Trust’s purchase of the Luckiamute Meadows property (Property), a 73.6-acre parcel of land located just east of Kings Valley in Benton County, Oregon. This conservation Property is located within a priority conservation area for riparian and aquatic habitats identified in the Oregon Conservation Strategy, adopted by the Oregon Department of Fish and Wildlife in 2006. One of the goals of the Oregon Conservation Strategy is to protect and restore native Willamette River tributary habitats and the species that rely on them. In addition, the Property is contiguous with an existing conservation easement creating a conservation zone of nearly 225 acres adjacent to the Luckiamute River that includes the confluence of the Luckiamute River and Price Creek. This funding partially fulfills commitments made in the 2010 “Willamette River Basin Memorandum of Agreement Regarding Wildlife Habitat Protection and Enhancement between the State of Oregon and the Bonneville Power Administration”.

Moss, Associate Professor 1 2nd Reader: Guy LiTala, Research Associate ACKNOWLEDGMENTS I have many people to thank for supporting me through the writing of this paper. First, I would like to thank Dr. Alston Thoms for writing his dissertation in the first place. It served as a continual reference guide, and remains the quintessential resource on camas thus far. He also graciously took the time to answer my many e-mails and provided notes. I would also like to thank Dr. Pam Endzweig, Dr. C. Mel Aikens and Cindi Gabai at the Museum of Natural History for allowing me access to the camas bulbs both on display and in the collection. I am also grateful to Pam for her continual encouragement and friendship; my time spent at the museum was among my best graduate school experiences. Thanks also to Dr. Guy Tasa for his statistics expertise and many engaging discussions about camas harvesting and selecting. I especially thank my advisor, Madonna Moss, for her tireless and thorough editing, and for validating and expanding my interest in gender and archaeology.

  • Henry Zenk September 8, 2006 the Kalapuyan Presence in Oregon's
    Henry Zenk September 8, 2006 The Kalapuyan Presence in Oregon's Geographic Names1 CALAPOOIA RIVER, CALAPOOYA MOUNTAINS. In Chinuk Wawa and other local languages, including the three Kalapuyan languages, /k,alaphu3ya/ was the usual general name for Kalapuyan speakers. The name has also been used more narrowly, to refer to all Central Kalapuyans or to one or another Central Kalapuyan group: in the Dayton Treaty of 1855, for example, it designates the Ahantchuyuk or Pudding River tribe, which occupied French Prairie, the part of the Willamette Valley extending from Champoeg south to Salem.2 The name evidently came into regional currency from Chinookan, where it has been recorded in the inflected forms /itk,alapúyawaykš/ (Clackamas dialect), /itgalapúywiyukš/ (Wasco and Wishram dialects). However, the stem forms themselves (/-k,alapúywa-/, /-galapúywi-/) appear not to be Chinookan, but of unknown origin. CHAMPOEG. According to some historical sources, this was originally a Kalapuyan village name.3h Gatschet recorded a3mpuik as the name of "a little town in French Prairie" located near a hill called in Tualatin / Va Vi3mapu3i Vuk/ 'place (in front of?) /pu3i h4uk/ (yampah, Perideridea sp.)'. While the name of the town and the name of the hill appear to be related, Gatschet's note is ambiguous as to whether hámpuik is really a proper Kalapuyan form, or just a Tualatin-speakers' pronunciation of the name of the historical Whites' town. It may be that the historical name "Champoeg" (historically /ch|m0pÇeg, /ch|m0poo0k, though usually heard now as /sh|m0pÇeg or even /sh|m0poo0) represents a contraction of, or a Whites' misconstrual for a more complete form.

    STATE OF OREGON DEPARTM ENT OF GEOLOGY AN D MINERAL INDUSTRIES 1069 State Office Building Portland Oregon - 97201 BULLETI N 35 {Revised Edition) 1964 GEOLOGY OF THE DALLAS AND VALSETZ QUADRANGLES, OREGON By EWART M. BALDWIN Professor of Geolog y University of Oregon Governi ng Bo ard Frank C. McColloch, Chairman Portland Fayette I. Bristol Grants Pass Harold Banta Baker Hollis M. Dole State Geologist FOREWORD TO THE FIRST EDITION The rec onnaissance geologic maps of the adjoining Dallas and Valsetz 15-minute quadrangles, together with the descriptive text in this bu lletin, are the results of work undertaken by the State geological su r­ vey . This important survey work was discontinued during the war and resumed in 1 946 . The two quad­ rangles are located in northwestern Oregon, mainly in Polk County, and cover a section of the summit and eastern slope o(the Coast Range and a portion of the western part of the Willamette Valley. The selection of the Dallas-Valsetz area for geological survey work stemmed primarily from the De­ partment's efforts to find limestone deposits of better quality than those now known in the area . Such de­ posits are badly needed both for industry and agricultural stone . The survey was not successfu l in finding commercial deposits of high-grade stone bu t information was obtained which indicates the favorable geo­ logical horizon where limestone deposits could probably be found and where further prospecting should be done. This stu dy of the area allows a clea rer understanding of stratigraphy, struc ture, and geologic history of the Coast Range .
