I've been on Lake Oswego many dozens of times but just recently noticed what I believe may be some sort of submerged ruins on the northern rim of the lake where Lake Oswego Rd. comes its closest to the lake. If you go to google maps, and zoom in to the area you'll see submerged linear features that measure about 100ft by 200ft with three two evenly spaced lines in the middle. I checked it out on historicaerials.com and it is visible on the 1951 aerials, but its pretty hard to see anything on the 1931 aerials. What is interesting though, is that the 1931 aerials show the land sticking much farther out into the lake, suggesting that a building certianly could have been there. Could this have been a part of the CCC camp? The 1951 pictures show the camp pretty well, which was located a bit to the east. I've also noticed some sort of ruins a little further east along the northern shore of the Oswego near where that canal? comes out at a little point. Any ideas? Old cranberry packing house that was blown out in a storm? CCC dining hall?
