Walk to the Rocks:  Geology of Tamanowas  Rock and Peregrine’s Rock, Chimacum, WA

The Trip—Lead by the QGS Rockstars

Tamanowas  Rock

On Friday, July 8, 2022, the QGS Rockstars (four of our geologists) will lead a 4-mile, 4-hour hike (11AM—3PM) from HJ Carroll County Park near Chimacum to the Tamanowas Rock Sanctuary, then up on top of Tamanowas Ridge to see Peregrine’s Rock.

The hike can be vigorous, steep, and rough in parts and is tailored to agile citizen scientists who are already knowledgeable about geologic principles and vocabulary. Subjects to be discussed include the glacial history of the Quimper Peninsula, specifically Chimacum Valley, glacial erratics on the Peninsula, and the geology of the underlying Eocene volcanic rocks. Tamanowas Rock is a special part of this story and a sacred place of the S’Kallum people.  Tamanowas Rock is the remnant of an explosive volcano that erupted about 43 million years ago.  It is comprised of Adakite, an unusual type of lava that forms under anomalously high temperatures when a subducted oceanic plate starts to melt.

Peregrine’s Rock, man for scale

Conversely, Peregrine is a glacial erratic named by Erik Nagel, a participant in our Great Erratic Challenge two years ago. It currently is the largest erratic documented on the Quimper Peninsula. The Rockstars are currently preparing a concise, illustrated guidebook (pdf), which will be emailed to all attendees in early July.  The field trip is limited to 50 hikers and requires advance registration (by snail mail) and a $15 fee (by check).  Deadline for RECEIPT of your form and check is Friday, July 1.  Those who register but exceed our limit may request to be placed on a wait list. The trip will run no matter the weather conditions, since the Rockstars will have travelled long and far to lead this trip.  Click on the the registration button below to download the required form.

Hi, I’m Carolyn Driedger, a Hydrologist and Outreach Coordinator at the U.S. Geological Survey in Vancouver Washington.   My science career began with research on glaciers and glacier-related hazards principally at Cascade Range volcanoes, and at Columbia Glacier Alaska. I witnessed the May 18, 1980 catastrophic eruption of Mount St. Helens and participated in the initial news media response.  This event set the course for several fascinating projects that crossed science disciplines, and it provided me with a front-row seat for observation and reflection upon the role of scientists in society. I’ve learned that scientists must use the same degree of creativity and care with public communication that they use with scientific endeavors.  Now, as CVO’s Outreach Coordinator, I work in partnership with public officials, emergency planners, media, park interpreters, and educators to advance the cause of eruption preparedness.  Some earlier career choices have informed my current work, including several years of teaching in a US public school and private school in Kathmandu Nepal, and working for the National Park Service.
