Someone recently started an online petition to encourage the preservation of the memorial. You can find out more here.
One of the best ways to protect the memorial from dismantling, is to have it listed in the National Register of Historic places. It takes a bit of work to get this done, but because the site has definite historic merit and integrity, it is a good candidate for such a listing. The Oregon State Historic Preservation Office agrees that this is a good candidate for a nomination, all that is needed is someone to take up the task.
Meanwhile, we’ve been told that a professional conservator has looked at the memorial and that it is certainly restorable.
