Where: Yeon Property, Warrenton
Led by: Tom Horning

Eventbrite - Dune Geology

Join North Coast Land Conservancy board member Tom Horning for a walk at Lewis and Clark National Historical Park’s Yeon Property near Sunset Beach. NCLC was honored to play a role in conserving this 100-acre property, includes 0.75 mile of oceanfront. We’ll hike on well-established trails beneath a canopy of pines that were planted in the 1930s by the Civilian Conservation Corps. After visiting the Yeon House and nearby lake, we will leave the trail and explore to the edge of the forest, where we will examine changing plant communities, the evolution of dune soils, and how all that is related to dune sand invasion over the last 100 years since jetty construction on the Columbia. We will wrap up at the interface of land and sea with a final stomp through vast stretches of dune grass to the beach and a stroll back to our starting point.

TOM HORNING grew up in Seaside and earned his master’s degree in geology at Oregon State University. He returned to Seaside in 1994 and opened Horning Geosciences, a geological consulting service. Tom joined the board of NCLC in 1996 and has been actively involved with the land trust ever since.

Walk Info: We will be walking on fairly well-maintained trail surfaces beneath an open pine canopy with patches of brush. Walking through beach grass is a bit more difficult. There is a public restroom at our trailhead at the Sunset Beach trailhead parking lot. Please leave dogs at home.

What to bring: Water and snacks-or bring a lunch and enjoy it at the end of the walk if you like. Wear sturdy walking shoes and dress for the day’s weather. Binoculars are always a good thing to have with you!
