Meet Us

The “Meet Us” page is designed to help you cross reference the staff/users/contributors of this site to the specific projects, pages or sites that they are involved in.  A great many people that should be are not mentioned here but instead can be found by visiting the specific web site, page or project that they contribute to.

“Staff” will be listed first to enable users to more quickly access the Willamette Valley Pleistocene Project specific resources that they may be attempting to find.

“Users and Contributors” of specific pages and web sites are listed next, in alphabetical order by last name.  These are the people that are the “bread and butter” of our website, each maintaining their own website or page to the benefit of all.



Mike Full;   Willamette Valley Pleistocene Project Founder and site administrator, site administrator for the Yamhill River Pleistocene Project.  A retired Police Officer, native Oregonian with a life long fascination with of fossils and prehistoric life.  As a young boy back in the mid-60’s he picked up a fascinating rock and decided to keep it. On another day, his river adventures lead him to a large projectile point. Years later these treasures were identified as a mammoth tooth and a Cascade point.  Since retiring, each summer finds him down on the river searching for fossils. One year he was rewarded by finding the fossil remains of a dis articulated mammoth weathering out of a cut bank of the river and he called in the experts. Forming the Yamhill River Pleistocene Project, we now have several in situ fossil locations and have identified the remains of mammoth, mastodon, giant sloth, extinct bison, ancient horse, giant camel, llama, deer, beaver and wolf; as well as a few projectile points, although the cultural component at any in situ location continues to elude us.  The Willamette Valley Pleistocene Project represents our attempt to bring together other resources, providing an overall picture of our Pleistocene past for the general interest of the public.
David Ellingson  Willamette Valley Pleistocene Project co-director and the Woodburn High School Pleistocene Site administrator. David Ellingson is a science teacher at the Woodburn High School, which sits atop Mill Creek: one of the richest Pleistocene mega fauna sites in the entire State.  It has yielded mammoth, sloth, bison and horse remains as well as a huge assortment of micro fauna and floral remains over a period of two decades.
David has been teaching biology at Woodburn High School since 1997 and has a deep love for American History, especially the Lewis and Clark Expedition and has been teaching a class that incorporates the history and science of Lewis and Clark.   In recent years he has been leading an investigation into the Pleistocene past right on the Woodburn High School grounds. He and his students are excavating a nearly complete ancient bison from the grounds. The size, completeness of the skeleton as well as the excellent state of preservation make it one of the finest Pleistocene mega fauna beasts ever excavated in Oregon. The bison is on display at the Woodburn High School in David’s classroom.
Joey Gill;    Web site developer, administrator, trouble shooter and all around computer SuperGenius. (She also takes time out in the summer to hit the river with us in search of fossils, old bottles and fun.)  Joey initially developed the Yamhill River Pleistocene Project web page and then took on the challenge of the Willamette Valley Pleistocene Project.  Her work paid off with a site that is hopeful extremely intuitive and user friendly that will be simple to navigate for both visitor and user.  She will be the resource to all users and contributors in need of assistance with their page, troubleshooting, additions and/or enhancements for individual pages on this site.  Additionally, Joey is a great professional photographer and is available for freelance work in that area as well.  If you like her product, need additional work done on your page or require some computer SuperGenius work done visit her web site at:
MarDee McDougal;    The photographer for the Willamette Valley Pleistocene Project and the Yamhill River Pleistocene ProjectI was born and raised in SW Idaho and graduated college in Portland with a BA in Speech and a Minor in Music.  As a child I collected fossils that I’d find in Succor Creek Canyon.  I have a Certificate from the New York Institute of Photography as a Professional Photographer and have taken several photography classes from both Portland Community College and Chemeketa Community College and am an active member of the Yamhill Valley Camera Club.  My specialty is the “outdoors” – whether it be wildlife, landscapes, or even flowers in my own yard.
I do professional free-lance photography and sell photos that I have taken and had core-foam mounted to your specs, so if you wish to contract my services (or arrange to obtain free pictures of our digs), you can contact me at .

Yvonne Addington is a founding member of the Tualatin Ice Age Trails program and has had a lifelong fascination with the history and pre-history of the Willamette Valley.  She is a former municipal judge, a retired City Manager for the city of Tualatin, a member of the Tualatin Historical Society and the leading expert on the history of the Tualatin Mastodon which is on display in the Tualatin City Library.  She has been a driving force behind the Ice Age Trails program, active in several of its projects, including tracking down, securing and arranging transport for enormous glacial erratic boulders now on display at the Historical Society.  Additionally, Yvonne has been a valued resource to the Willamette Valley Pleistocene Project, providing information and resources that has lead to several more investigations into our Pleistocene past, both within her home area of Tualatin and throughout the northern part of the Willamette Valley.
Dr. Robson Bonnichsen, PhD and the Center for the Study of the First Americans, Dr. Bonnichsen’s work and accomplishments were nationally and internationally recognized, yet he found the time to help the Yamhill River Pleistocene Project crew whenever we called; participating in a scouting float of the river, conducting the first exploratory dig at the McMinnville Site and producing two papers on the “McMinnville Mammoth”. His death in 2004 deprived us of more than a valuable resource; it took away a friend and he is sorely missed. The Center for the Study of the First Americans, with Dr. Mike Waters as its director, remains one of the foremost institutions studying paleo-archeology in America today and has carried on Dr. Bonnichsen’s tradition of assisting us whenever we have called upon them. Its mission is “exploring the questions surrounding the peopling of the Americas.” Visit the Center at their website:

Cory Eklund and the McMinnville High School Site:  Cory grew up in central Montana, surrounded by active dinosaur digs. He caught the bug early and loved visiting museums, and playing in the dirt pretending to be a paleontologist. He majored in Earth Science at Oregon State University, and also holds a Masters in Science Education from OSU. Cory has taught at McMinnville High School for the last five years, but uses his summers to explore the awesome world of Paleontology. He has volunteered at the Wyoming Dinosaur Center working on Jurassic aged dig sites, and hopes to volunteer at the Academy of Natural Sciences this summer in Philadelphia. Cory also offered a class on paleontology at the high school and has had incredible interest from the students. In the last couple of years, over 200 students have taken his course and learned about ancient earth. Some of his former students have even gone on to study paleontology, geology and archeology. Cory also hopes to go back to school soon himself, and pursue his passion of paleo!



Dr. Lyle Hubbard, PhD I am an hybrid in training and in how I view this planet.Majored in Biology (ecology) with history and philosophy.Then earned a masters in Biological Oceanography and went to sea (Pacific and Bering) lots.  Then changed course, took a masters in Biological Anthropology, adding more work in Geology.  Finished up the formalizing of my educational experiences with a terminal degree in Biological Anthropology and

paleoecology. Have worked in Alaska, the Northwest, Tennessee and Kriti. My work has been behind the podium and in the field in all of the above areas.

All I really want to do is collect bones, teach (pedagogically) and contemplate the historical threads of this ball of yarns.

Dr. William Orr, PhD, professor emeritus and curator of the Thomas Condon collection of fossils at the State Museum of Fossils located at the University of Oregon, is our scientist in oversight. He and his wife Elizabeth have literally “written the books” on Oregon fossils and the geology of the northwest. Now semi-retired, he still teaches, lectures, consults and somehow finds more time for us than we deserve. Dr. Orr has spent countless hours of his own time teaching us the basics of vertebrate paleontology, taxonomy, methodology; training us in field work and identifying fossil specimens.   He has brought by specimens from the Condon collection for comparison, coordinated with our on-scene scientist, and lent his experience and counsel in a huge number of factors that have kept our projects on track.

His current project is a late Pleistocene mega fauna dig site in Kings Valley that continues to yield exciting finds each summer.  Visit the Condon Museum at the University of Oregon web site:


Dr. Alison T. Stenger, Ph. D. is the director of research for the Institute for Archaeological Studies and our on-sight scientist. She was the field director of the Woodburn Paleo Archaeological Project, where her team succeeded in identifying many species of extinct Ice Age fauna and extracting an ancient human hair from the late Pleistocene bog deposits. Her contacts at the La Brea Museum are a tremendous resource to us, positively identifying sloth, mammoth, mastodon, giant bison, extinct camel, ancient horse and bighorn sheep from our sites in 2007 and 2008. Additionally, she has shared her knowledge of projectile points with us, to aid in the identification of the few scattered surface finds we have documented. The Institute for Archaeological Studies is a non-profit, education and research organization, doing mostly State and Federal projects, but occasionally private contracts. The Institute does field work, lab work, and papers on its projects; they will stabilize and catalogue specimens, but they do not curate collections. Check out their website at:


Dr. Michael Southard, PhD  I earned my BA in anthropology from Southern Illinois University, Carbondale and earned my advanced degrees in anthropology from the University of Oregon.  I have worked on archaeological excavations in Illinois, Missouri, Oregon and Washington.  I managed the facility and oversaw excavations at a Middle Mississippian fortified ceremonial center at Towosahgy State Archaeological Site in Missouri in the early 1970’s.  Between 1975 and 2005 I served as the archaeologist/cultural resource manager for the Eugene District, Bureau of Land Management.  I believe my favorite experience excavating sites occurred during the Carlyle (IL) Reservoir Salvage excavations in the early 1960’s.  We were excavating a series of Middle Mississippian farmstead sites.  After excavating some test pits to get an idea of what material was in the plow zone the boss would hire heavy equipment to come in and peel off the plow zone.  The entire farmstead complex would be exposed.  We would map the location of all of the features and then proceed to excavate and record the details of each feature.  The best was a burned house which collapsed and preserved carbonized materials including cordage and structural members of the building.


Rick Thompson and the Ice Age Floods Institute  A native Oregonian, Mr. Thompson is President of the Lower Columbia Chapter of the Ice Age Floods Institute who loves to share the beauty and natural history of the great Northwest through art, photography, writing and public speaking.  Though geology is not his profession, it is his passion.  Being intrigued by the land formations, huge boulders and glacial erratics, he embarked on a twelve-year study of the effects of the ice age floods on NW Oregon and SW Washington.  His interest in rocks and fossils dovetails with his present pursuit of the Lake Missoula Flood.

Besides giving PowerPoint talks and leading field trips, Mr. Thompson has developed a number of driving tours and is currently in the process of completing a book on the subject, illustrated with his own photographs, maps and diagrams.
