Author, geologist, instructor, and photographer Ellen Morris Bishop presents Hell Unleashed: Flood Basalts, Extinctions, and the Death of Dinosaurs, Friday, August 19, at Columbia Gorge Discovery Center & Museum, 5000 Discovery Drive, The Dalles. A pre-program dinner begins at 6 p.m. followed by the 7 p.m. program.
Dinner includes: breaded tuna steaks and creamy noodles, lemon garlic asparagus, garden salad, dinner rolls, and brownies.
In combination with stunning photography, Bishop presents a riveting program on the massive lava flood basalts which have occurred around the world over hundreds of million years, and their effects on the entire planet.
Long before the Ice Age, the earth erupted flood basalts—molten rock that covered tens to hundreds of thousands of square miles—many times. They were both creator and destroyer in the geologic record, leaving behind traces of their passage that shaped life and the landscape we see today.
They include the Deccan Basalts of India, that coincide with the extinction of dinosaurs, and the Siberian Basalts that coincided with the extinction of 95% of life on Earth some 252 million years ago.
The Columbia River Basalt exposed throughout the Columbia River Gorge are mostly 16-14 million years old, and a relatively benign result of flood basalt eruptions.
But there is a kinder, gentler side to these eruptions. Flood basalts are implicated in saving the planet from perpetual entombment in ice, and the blossoming of the first complex life. They may have led to the rise of dinosaurs, as well as their extinction.
This event is co-sponsored by the Gorge Chapter of the Ice Age Flood Institute.
The 6 p.m. tuna steak dinner and 7 p.m. program are $18, the program only is $5. Reservations must be made by August 17 by calling 541-296-8600 ext. 201.
