. A new church was built and served until 1927, when the current building replaced it. The church is located east of Camp Rilea. The Pioneer cemetery established in 1846, making it the oldest in the county, is the burial place for many early settlers. A community called "Clatsop Plains" was established and incorporated in 1870, primarily for the purpose of restricting cattle grazing along the sea ridge. This grazing was destroying the ridge grass and plants that prevented sand from blowing onto the nearby farms. As incorporated originally, "Clatsop Plains" extended from the Skipanon River to Seaside. An actual town eventually came into being about a mile north of Seaside, and was later absorbed into Gearhart. However, its early proximity to Seaside is probably why Seaside itself was sometimes referred to Clatsop Plains. The coastal grassy areas of Clatsop Plains was home to the
