The Geology of the Seal Rock Area has just been released and is available for download on line. The publication covers many aspects of the basalt, sandstone and sea cliffs that are visible along the beach between Alsea Bay and Ona Beach State Park. It also includes a section on Yachats Basalt, and briefly mentions the basalts of Yaquina Head, Cape Foulweather and Depoe Bay.
The Geology of the Seal Rock area was written by local resident Maxine Centala of Seal Rock, who had wished for better nontechnical information about local landforms, and decided to fill that gap. It covers topics such as sedimentary rock, basalt, paleontology, buried forests, marine terraces, changing sea levels and earthquakes. The text is accompanied by over 100 photographs, maps, diagrams and a list of references, all designed to help local residents and interested visitors learn about the rocks and landforms found here and how they came to be.
