2024-06-21 Dr. Garrison-Leavy and Dr. Peck – Discovery Bay Tsunami Evidence

FRIDAY June 21, 2024  (9 AM)
FIELD TRIP:  Examine Discovery Bay’s Past Tsunami Record Using Two Contrasting Evidential Methods

There are at least two salient features of Pacific Northwest history:  an extremely active geologic past, coupled with a region inhabited by indigenous peoples since “time immemorial”.

These two features share common ground at Discovery Bay on the Quimper Peninsula of Washington State. Many tsunamis have occurred at this bay over at least the past 3000 years, during which time the area was concurrently inhabited by indigenous peoples.

This field trip will examine the geologic and anthropological evidence of the occurrence of multiple tsunamis in Discovery Bay. Our field trip leaders, Dr. Carrie Garrison-Leavy (geologist) and Dr. Alexandra Peck (anthropologist), are active researchers in their respective fields, which are specific to this topic. They will lead us through an examination of the possible link between tidal marsh tsunami sedimentation and indigenous oral histories as contrasting evidential methods of recording tsunami history.

About the Speakers:  Carrie Garrison-Leavy and Alexandra Peck

 

 

 

 

 

 

Dr. Carrie Garrison-Laney is a Coastal Hazards Specialist at Washington Sea Grant and a liaison to the NOAA Center for Tsunami Research. A focus of Carrie’s research has been the age and distribution of paleo-tsunami deposits with lessons learned from historical events. She earned her PhD from the University of Washington.

 

 

 

 

 

 

 

 

Dr. Alexandra Peck is professor and Audain Chair in Historical Indigenous Art at the University of British Columbia. Trained in archaeology, her research explores pre-colonial Native life, cultural change, and social interactions on the Olympic Peninsula. With extensive academic publications, she is also co-editor of Archaeology in Washington.

TO REQUEST REGISTRATION:

Equipment Requirement:  Wetland participants must come equipped with at least knee-high boots since the tsunami sediments are exposed in a tidal marsh. This will be messy but fun!!!!

TO REQUEST REGISTRATION:  Complete the form below; leave no blanks; must be legible; one form per person/couple. In your comments, tell us if your request is contingent on another person also being registered and provide their name. No pets allowed. ADA accessibility is not possible due to site conditions.

Mail your completed form and payment of $20.00 each

(check made out to:  “Jefferson Land Trust”)

Send to:  Michael Machette, 120 Fairbeeze Drive, Port Townsend, WA 98368

Requests should be received by June 7. The number of trip participants is limited, first come, first reserved. If the field trip is full before we receive your request, your name will be put on the wait list (if you have requested it), and your check will be held in case a space becomes available. If we cannot register you, you will be notified, and your check will be voided and shredded. If you must cancel your registration at any time, notify us ASAP. If we fill your space from the waitlist, we will shred your check. Otherwise, your full payment will be forfeited. QGS will use the money as a donation.

You will be notified by email of your registration or wait-list status. As the trip date nears, you will receive specific trip information including what to bring (i.e., lunch, water, binoculars, hand lens, etc.). Carpooling is requested as parking spaces will be limited. The trip will begin at 9:00 a.m. and last approximately two hours. Meeting location will be provided with email to participants in early June.

Carrie suggests for the wetland portion of the trip:

“Be prepared to get muddy. You might want to bring a change of clothes and shoes to put on before getting back into your vehicle. Consider bringing a trash bag or bucket to transport your muddy things.  Wear chest waders if you have them. You can get by with snug-fitting hip boots, knee-high boots, or lace up boots that can get muddy, perhaps paired with rain pants. The mud sucks loose-fitting boots and shoes right off your feet, so sometimes people wrap duct tape around the ankles of their boots to make them extra snug. Water sandals are not a good option unless they are closed toe (and tight fitting) because there are sharp things out there that will poke your toes. I recommend bringing gardening gloves to keep your hands somewhat clean and protected. In addition, bring rain gear, warm layers, water, snacks, a sun hat, sunscreen, and anything else you might need to be comfortable in a tidal marsh for a couple hours.”

2021-10-02 Ian Miller & Keith Denton — Field Trip: A decade of changes in the Elwha River as a result of dam removal

Quimper Geological Society Field Trip

October 2, 2021, Port Angeles Area

One-day field trip (car caravan) to see the Elwha River’s response to removal of its two dams 7 years ago (2014).  We’ll see the lower dam site, one of the dissected lake basins, sedimentation along the river’s mid-reach and the build out of the river’s delta. Ian Miller, our geologic guide, is with the SeaGrant program of the University of Washington, but resides in Port Angeles close to the action.  In addition, we recruited Keith Denton to talk about the main reason for the dams removal (fish)   Keith is a Fisheries Consultant and will discuss the recovery program that has brought salmon back to the Elwha River after a century.

Leaders:  Ian Miller, Coastal Hazards Specialist, Washington Sea Grant, Port Angeles
Keith Denton, Fisheries Specialist and Consultant, Sequim
Michael Machette, Quaternary Geologist (retired), Port Townsend

Objectives:  Visit ground zero of the largest dam-removal project in the world and one of the largest ecological restoration projects ever attempted. See the developing shore-line and take a tour of three important restoration sites along the Elwha River. Enjoy the outdoors and have enlightening discussions (socially distanced).
