Local geologist Tom Horning will speak at the Listening to the Land series Jan. 21.

The Earth is in a constant process of rebuilding itself, and Oregon’s North Coast is no exception.

Join Seaside geologist Tom Horning on a journey through time and space in “Rising from the Sea,” this year’s first Listening to the Land program, at 6 p.m. Jan. 21, in the Seaside Public Library.

Admission is free. Refreshments are served.

The mountains that define the eastern horizon were once a volcanic sea floor covered by thousands of feet of mud and sand, and the most familiar headlands are remnants of North America’s largest lava flows invading the coast. Horning will explain how these and other elements of the local landscape changed over time — and are continuing to change.

Horning 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 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.
