Oregon: A Geologic History
Oregon: A Geologic History wall poster 150 Years of Statehood, 150 Million Years in the Making!
The spectacular landscape of today's Oregon was shaped over millions of years by fire and flood, earthquakes and eruptions, and the movement of oceans and continents on a huge scale. Learn more with the release of "Oregon: A Geologic History" (Interpretive Map 28, by Ian P. Madin). This map was created for anyone who is curious about our State's remarkable geology. On this huge 4 foot by 5 foot full color map, a timeline outlines important events in Oregon's (and the earth's) geologic history. Each rock layer has its own story and you can find out where to go to see the rocks for yourself. World class geologic events are highlighted, and there are plenty of factoids to keep you intrigued to learn more.
