Monday, January 6, 1:30-3 p.m., Orcas Senior Center
— from Lena Kassa for Orcas Senior Center —
Due to the overwhelming response in November, Orcas Senior Center will be hosting a repeat Geology of Orcas Island presentation by local experts, Julia Turney and Michael E. Yeaman, Monday, January 6, 1:30pm-3:00pm. Come learn about the complicated and unique geology of Orcas Island. The first half of this 90-minute workshop will cover geologic principles including rocks and minerals, plate tectonics, geologic maps, geologic time, and how we read the history of the earth from its rocks. The second half will focus on Orcas Island bedrock formations—from the Turtleback Formation to the Nanaimo Group—and on the young glacial sediments that lie above them. We’ll also bring some Orcas Island rock samples to examine and talk about.
Julia Turney has a bachelor’s degree in Geology from California State University in Sacramento and is retired after a 30+ year career working in Colorado, California, and Washington in environmental and engineering geology. She lives on Orcas Island and is a licensed geologist in Washington and California.
Michael E. Yeaman has a bachelor’s and master’s degree in Geology and Geophysics from Stanford University. He worked in the energy and consulting industries for 30 years before moving to Orcas in 2004. He has given lectures and conducted fieldtrips on the geology of the San Juan Islands for the past decade. At present, he devotes much of his time to stone sculpting.
