Easy: Driving tour with short walks

The stunning beauty of the Columbia River Gorge region belies its tumultuous geologic history, which spans about 50 million years of volcanic arc activity, massive flood basalt eruptions, massive tectonic forces, catastrophic Ice Age Floods, huge landslides, and intense earthquakes. We’ll explore much of that tumultuous geologic history, and visit some of the stunning geologic wonders resulting from that tumult.

Join leader Lloyd Dekay*, president of the Columbia Gorge chapter of the Ice Age Floods Institute (in place of Jim Chase) for this informative geology tour on both sides of the Columbia River. This driving tour, chartered by Martin's Gorge Tours, includes numerous stops and short hikes to learn about the Gorge’s unique geology and ice age floods remnants.

*Lloyd DeKay is a retired geologist and president of the Columbia River Gorge Chapter of the Ice Age Floods Institute. He has a Master’s Degree in Geological Oceanography and had a 27 year career in international oil exploration, working on projects in various parts of South America, Africa, SE Asia, and Europe while living in Houston, San Francisco, Nigeria, and New Orleans. His first exposure to the Gorge was a 1976 temp job with the Corps of Engineers working on the Bonneville Dam second powerhouse, and that exposure led in part to his retirement to White Salmon in 2007. Since then he’s had to learn about a whole new geological realm as he’s led field trips and given presentations about local geology on behalf of the Ice Age Floods Institute.

$40 fee/person includes lunch at Freebridge Brewing and transportation.
