Dynamic Geology of Oregon
With Scott Burns, professor Emeritus of geology at Portland State University
Oregon has an incredible history geologically which has led to many different geographic regions of the state with many different characteristics and history. Over 150 million years ago, the whole state was under water. Through time, ocean bottom and islands have been “stuck on” the North American continent through the process of accretion. 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. Recent discoveries of many ancient large volcanoes in eastern Oregon, one being centered on Prineville, have been very exciting. Dr. Burns will take you around the state showing the different provinces and how they were formed and how they are all related in a dynamic presentation on the incredible natural history of our state.
Scott Burns, PhD, is a professor Emeritus of geology and past chair of the Department of Geology at Portland State University where he has taught for over 20 years. He has a B.S. degree in chemistry and a M.S. degree in physical sciences from Stanford University and a PhD in geology from the University of Colorado, Boulder. Dr. Burns specializes in environmental and engineering geology, geomorphology, soils, and quaternary geology. In Oregon, his projects involve landslides and land use, environmental cleanup of service stations, slope stability, earthquake hazard mapping, the Missoula Floods, paleosols, loess soil stratigraphy, radon generation from soils, and the distribution of heavy metals and trace elements in Oregon soils and alpine soil development. He has won many awards for outstanding teaching and his work in geology, including the Distinguished Faculty Award from the Portland State Alumni Association in 2001, the Richard Jahns Award for engineering geology from GSA and AEG in 2011, and the Outstanding Scientist for Oregon for 2014 from the Oregon Academy of Sciences. He has authored more than 100 publications and received more than 25 research grants. Dr. Burns actively helps local TV and radio stations and newspapers bring important geological news to the public and, for the past 43 years, has been studying wine and terroir—the relationship between wine, soils, geology, and climate.
