09-29-2018 John Pallister: Volcanic Disasters and Hazards to Aircraft


Sat. Sept, 29, 3-5 pm; John Pallister—VDAP & Volcanic Hazards to Aircraft

Meeting Location
Port Townsend Aero Museum
105 Airport Road
Port Townsend

This special venue is a private museum dedicated to preserving aircraft history of the Pacific Northwest through restoration, maintenance, and repair of aircraft.

About the Lecture

In this talk, John Pallister (U.S. Geological Survey) will describe the Volcanic Disaster Assistance Program and how volcanic eruptions can have disastrous consequences for aircraft.  Until recently, most radar systems did not image the ash plumes from volcanic eruptions and aircraft may well fly through the plume without prior warning. The silica-rich ash can destroy jet engines in minutes and lead to catastrophic results.  Hence the link to the Aero Museum, which seemed to be a fitting venue for the talk.  A $10 donation is required; this includes access to the museum at 3 pm and the hour-long talk starting at 4 pm.

A telemetered, solar-powered scanning spectrometer was installed in 2016 at Sinabung Volcano in Sumatra, Indonesia. It measures sulfur dioxide gas emissions, which helps forecast volcanic activity.  This is one of many activities sponsored by VDAP.


About the Speaker

John Pallister is a recently retired Senior Reseach Geologist at the U.S. Geological Survey in Vancouver, WA.  John has a long, varied and distinguished career, most recently as coordinator for the USGS’s VDAP program. VDAP is the Volcanic Disaster Assistance Program, an international project to monitor volcanic eruptions around the world.

01-20-2018 Brandy Rinck: Geoarcheology

About the Talk

Geoarchaeology in Washington: Hidden Landforms and Buried History

Brandy Rinck presents the multi-disciplinary approach that uses methods and techniques from geology, geography, and other Earth science fields to study archaeology. This presentation considers how geoarchaeology applies to the field of cultural resources management in Washington State through example project descriptions and archaeological site accounts from the north coast of the Olympic Peninsula, the Puyallup River delta front, and the Chehalis River basin.

Archaeological sites on the Olympic Peninsula are often unique in type and some contain evidence of the first people to arrive in the region after the Last Glacial Maximum. This presentation includes a brief overview of current theories on human migration and initial occupation of the area. The presentation will include artifact and site photographs. Replica stone tools and stone tool byproducts will be available for attendees to handle at the end of the talk.

The end goal of this presentation is to explore the archaeological sensitivity of western Washington through the lens of geoarchaeology in order to understand why different depositional environments carry a diverse potential for encountering buried cultural materials at variable depths. When utilized by planners and developers, geoarchaeological data can focus archaeological field survey efforts and plan future project ground disturbance in order to increase efficiency and decrease costs.

About the Speaker

Brandy is a geoarchaeologist with King County Parks and Recreation in Renton, WA. She got degrees in Anthropology and Geology at SUNY Geneseo, followed by an M.A. in Geoarchaeology at Boston University. Ten years ago, Brandy moved to the Pacific Northwest to work in the field of Cultural Resources Management for a private firm in Seattle. She is extremely active in a number of Geology and Archeology groups in Puget Sound.

04-14-2018 Let’s March for Science

Sat. April 14, Seattle

Jefferson Land Trust Geology Group will march. The Seattle route map, access, and FAQ’s are now posted on the March for Science website.

We’ll post details about our involvement about a week before the event.  Carpooling, how to get from the ferry to Cal Anderson Park (start point), duration, etc.  If you have specific questions, contact me at Paleoseis@gmail.com
