Lloyd DeKay of White Salmon will concentrate on the Ice Age Floods that developed some of the geologic wonders and beauty we marvel at today. The History forum will take place Feb. 4, at the Original Courthouse in The Dalles at 1:30 p.m. The stunning beauty of the Columbia River Gorge is the result of 50 million years of volcanic arc eruptions, massive fissure eruptions of flood basalts, catastrophic sediment-saturated Ice Age Floods, huge landslides, and massive earthquakes.
