I’m writing a geology guide book!

Dear friends and subscribers,

I have a contract to write Geology Underfoot in Western Washington, to be published by Mountain Press Publishers (Missoula). Some of you already know this, but here is advance notice to the rest of this website’s readers.

Folded turbidites north of Kalaloch, Olympic Coast of Washington. From a vignette in Geology Underfoot in Western Washington. Click to enlarge.

The book will present 27 or so field trips in the form of separate vignettes. These will provide guides and explanations to particularly interesting places in western Washington, from the Columbia River to Mount Baker, and from Washington Pass to the Olympic coast. The intended audience is people with an interest in natural history; a geology education is not needed. The sites are chosen based on road accessibility and clarity of rock or landscape exposures. There will be optional hikes associated with most if not all of the field trips. Each vignette discusses a particular location in considerable detail, including some geologic background. I will have geologists, such as Brian Atwater, Russ Evarts, Maury Schwartz, and Kevin Scott, who are knowledgeable about the particular locations, review each vignette; I’m still rounding some of these folks up. The introduction will explain some basic principles – plate tectonics, a little about rocks and minerals, the methods used to date geologic events and rocks. . . stuff like that. There will be many color illustrations: maps, photographs, and diagrams.

A few of the sites are: the guts of a volcano at Beacon Rock; the mythical ‘Bridge of the Gods’ landslide near Bonneville Dam; a Columbia River basalt lava flow in western Washington; trees drowned by in the January 1700 M 9 earthquake in Willapa Bay; the Mima Mounds south of Olympia; Chuckanut honeycomb structures; submarine pillows at Hurricane Ridge in the Olympics;  development of Dungeness Spit; the Kulshan caldera at Artist Point; and a choice erratic or two. Each vignette is 6-10 printed pages.

The book will be widely distributed in bookstores, National Park and National Forest visitor centers, and on line from the publisher and various distributors. My press deadline is April 30th, so don’t hold your breath. Since I need to buckle down and get a lot more text written, maps made, and figures drawn, this Northwest Geology Field Trips website will have fewer updates for awhile. Please don’t go away.

Mountain Press Publishers also produces the popular Roadside Geology series. The Geology Underfoot series is better if you prefer hands-on geology and detailed descriptions. So far there are volumes about Yosemite, northern Arizona, southern Utah, central Nevada, Illinois, Death and Owens valleys, southern California and, rumored to be coming soon, Yellowstone.

Best to all,

Dave Tucker

  1. Great! I’ll buy a copy as soon as it hits the shelves.

  2. That’s awesome. Congratulations. Looking forward to reading it. Nice folded turbidites, BTW.

    • They are nice turbidites, Callan, and they are pretty young, too: Miocene. Deposited off the leading edge of North America onto the Juan de Fuca plate, they were shoved back to the east during accretion associated with the plate collision and uplifted to just barely above sea level. They moved 80 miles in a pretty short period of time, 18-24 million years. They will be the subject of a vignette in the book.

  3. Awesome! I can’t wait.
