D. B. Cooper and Flight 305: images of Tena Bar

Once in a while, my Freedom of Information requests got lucky. Here's a pro-active response from the US Army Corps of Engineers:

"This responds to the subject Freedom of Information request ... for “higher resolution copies of images from a former dredging at Tena Bar, Columbia River in 1974 ... referring to photographs furnished by Waterways Maintenance Branch, Navigation Division, U.S. Army Engineer District, 319 S.W. Pine, Portland, Oregon." All images the Portland District has relative to your requested area are attached. I trust the documents fully satisfies your request. ... Due to the time required to process your request, all associated costs above the two-hour threshold were waived."

Those images did indeed fulfil my request, and more. They greatly enhanced my understanding of the changing shape of Tena Bar between 1974 and the present day. That became part of the story of Chapter 11 "Tena Bar".
