Geology Underfoot in Western Washington has gone to the printers, and should be on store shelves the end of April or early May. Start bugging you local bookstore to get orders in now. Here’s the book’s cover. It is an oblique view of Mount Rainier during a moderate eruption, made by Eric Knight, and is modeled in part on the 500-year-old Electron lahar. Eric painted the bird’s-eye-view in an arc looking from the north  to the southeast, from the Tacoma Tideflats around to the erupting volcano. There is a lot of detail. Look closely and you will see lahars descending the northwest and western flanks into the Mowich and Puyallup River valleys. The boiling cloud of a pyroclastic flow is on the right, covering the Tahoma Glacier. The lahars coalesce and inundate the Puyallup valley. That’s Lake Kapowsin at lower right. A short distance downstream from the lake, the lahar passes through the center of Orting, which appears seriously damaged and on toward Puyallup and Tacoma. The lahar would likely have a much reduced sediment load by this point, and be more of a hyperconcentrated flow- predominantly extremely muddy water rather than a dense slug of mud. The muddy flow enters Puget Sound at Commencement Bay, having sloshed mud and water all over the Tacoma tideflats industrial area. Suspended sediment has discolored Puget Sound most of the way to Elliot Bay at Seattle. There’s not enough detail in this image to tell, but I-5 appears intact where it crosses the Puyallup. In this hypothetical eruption, no lahar has entered the White River valley so the Auburn-Kent-Duwamish area has been spared.

Erik also did the cover art for Geology Underfoot in Yosemite National Park. He makes wonderful panoramic maps. Visit his website to see a fine panoramic painting of the Salish Sea. It is interactive, so you can zoom in, pan very different perspectives. The tool bar at the bottom includes a ‘help’ button for instructions.

  1. Congratulations Dave. I look forward to reading it.

  2. Wow, novel idea for a cover! Can’t tell by the depiction if the hoped-for Bridge for Kids had been built at Orting by the time of this fictitious (yet inevitable) eruption and lahar—time will tell.
