From the Painted Hills to Smith Rock to the Columbia River Gorge, Oregon’s incredible geological history has shaped the beautiful and diverse terrain here at home. On this Nature Night, Dr. Scott Burns, Professor of Geology at Portland State University, will show you how the different provinces were formed and how they are all related in a dynamic presentation on the fascinating natural history of our state.
Over 150 million years ago, Oregon was under water. Through time, the ocean floor and islands have been “stuck on” adhered onto the North American continent through the process of accretion, the gradual accumulation of layers. The Blue Mountains and the Klamath Mountains both have their origin in accretion and are the oldest rocks in Oregon. Many different volcanic events have covered Oregon with layers of different igneous rocks. The influence of the Juan de Fuca plate being pushed under Oregon from the west has led to uplift of marine rocks creating the Coast Range, the Cascade volcanoes and large subduction earthquakes. Recently, there have been exciting discoveries of many ancient large volcanoes in eastern Oregon, one being centered on Prineville. We hope you’ll join us to learn how the Oregon we know and love was formed, creating a multitude of habitats for the people and native wildlife who live here.
Named 2014 Outstanding Scientist by the Oregon Academy of Science, Scott Burns has been teaching geology for over 44 years! The last time he presented at Portland Audubon many, unfortunately, had to be turned away. This Nature Night will be at Montgomery Park to allow for all interested to attend. So come early and see what all of the talk is about.
