What You’ll Do

Although Seattle’s buildings look modern, the stones used to make them are actually much, much older than they appear. During this two-hour tour of the downtown area, you’ll follow around naturalist David B. Williams as he points out examples of stone architecture built out of granite, sandstone, and other rocks as old as 3.5 billion years. All participants need bring is a sense of wonder—and maybe a magnifying glass to get an up-close look at some of the stones.

David B. Williams
Author and Naturalist

After moving from Utah to Boston, geologist David B. Williams longed for the red rocks of the American west. That is until he discovered ancient sandstone, fossils, and other geological treasures hidden right in the city’s stone buildings. Since then, the naturalist has lectured on the geological history of building stone, authored numerous books on the subject, and led Stories in Stone building tours for two decades.
