Seaside — The Earth is in a constant process of rebuilding itself, and Oregon’s North coast is no exception. To further explore this constant change, Seaside geologist Tom Horning will present a journey through time and space in “Rising from the Sea” to kick off this year’s first Listening to the Land program at 6 p.m. Wednesday, Jan. 21 at the Seaside Public Library. Admission is free. Refreshments will be served.

The mountains that define the eastern horizon were once a volcanic seafloor covered by thousands of feet of mud and sand; and the most familiar headlands are now remnants of North America’s largest lava flows that once invaded the coast. Horning will explain how these and other elements of the landscape changed over time and continue to change.

Horning, a Seaside native, has a master’s degree in geology from Oregon State University. After a varied career as an exploration geologist, he returned to Seaside in 1994 and became a natural hazards and geotechnical consultant doing business as Horning Geosciences.

Listening to the Land is a monthly winter speaker series presented by North Coast Land Conservancy and the Necanicum Watershed Council in partnership with the Seaside Public Library and with generous support from the Seaside Chamber of Commerce. This year’s Listening to the Land series is focused on the natural and cultural heritage of the Oregon Coast.
