|1953 USACE aerial photo of Bayocean from Oregon Coastal Atlas|
Anyone interested in Oregon's coast should know about the Oregon Coastal Atlas. Whether your focus is history, environmental issues, shoreline changes, storm and/or tsunami planning, or photographic timelines, this site offers a plethora of data, and digital tools that bring it all to life. Some if the information is not available elsewhere. For example, their Estuary Data Viewer is the only place I've found that provides a township and range map layer for Bayocean.
Back in 2002 Tanya created a web tool for Coastal Atlas called Tillamook Bay: The Erosions of Bayocean Spit . She took it down some time ago, but has just reposted it. I could only dream of being able to put something like this together, so I am very pleased she's done this. By moving your cursor across years ranging from 1939 to 1964 you'll see a series of aerial photos taken by the Corps of Engineers, visually depicting the slow destruction and eventual rebuilding of the spit. Enjoy it.
