Volcanic activity is the dominant geologic agent shaping the Central Oregon landscape! We live on a thin piece of crust near the edge of an active continental margin. That activity is tectonics, pieces of earth's crust in motion.
This motion results in volcanic activity. Different types of crustal movements produce different types of volcanic rocks. Volcanic activity is very much in evidence with the Cascades to our west and lava flows exposed throughout the Deschutes Basin. Almost all the rocks in Central Oregon are volcanic or are directly derived from volcanic rocks.
Attendees will have the opportunity to examine a variety of rock samples and observe and compare their characteristics such as color, density, and texture. Each rock type will be discussed in terms of their composition and physical characteristics and how these characteristics relate to the tectonic environment that produced them.
Al Albin grew up in the Willamette Valley and always had an interest in geology. He moved to Eastern Oregon and worked at the John Day Fossil Beds. His experiences with the professionals that worked and studied there inspired him to study geology in earnest. Al received his Bachelor’s Degree at Oregon State University and his Master’s Degree at Northern Arizona University. He worked as an engineering geologist with the US Bureau of Reclamation and the Department of Agriculture. After retiring, he returned home, to Central Oregon where he leads geology hikes for FANs.
