A Rockhound’s Guide to Oregon & Washington, written by Alison Jean Cole, is a collection of 60 sites where you can explore ancient sea-floors, epic lava flows, glacier-carved landscapes, and evidence of 200 million years of tectonic action throughout the PNW. Discover agates and jaspers in the volcanic Cascade Range and marine fossils along the Oregon Coast. Search for concretions along the Olympic Peninsula, petrified wood in the Owyhee Uplands, and much more.In addition to detailed information on where exactly to begin a rock hunt, every location features an overview of the area’s geologic history and age, what types of rocks are worth finding there, needed tools, land manager, and collection limits. Clear driving directions with GPS coordinates, road quality and trip safety information, best season to go, and an informative map round out each description.
Alison will sign books and chat with museum guests about her work, rockhounding with care, and has a demonstration that is excellent for beginning and experienced rockhounders alike!
