Very interesting! I was particularly interested in the Google Satellite Image search. If I had time, I would give it a whirl. I'm pretty skilled at aerial photo interpretation.
As a matter of fact, I've found two separate anomalies in areas that I'm familiar with and I intend to visit them on the ground.
One was a ring-shaped pattern a few hundred feet across near an old cabin that I explored two summers ago with my oldest buddy. I found that while doing a Google Earth study of the site. I'm sure it is a conifer root rot colony. Phellinus weirii, or Armillaria mellea. Like a mushroom ring, a really big one.
The other is a geological feature, I'm sure. It's right smack on my old trapline, but as it was always under snow when I was trapping I never noticed it then. Of course, that was almost fifty years ago.
A P-51 Mustang crashed near Sandy Oregon, and I used to talk about it every time we drove by. I never walked in to the site, but it was a well-known local feature.
The only plane I found was in the bottom of Big Sand Lake, which happened to be on the souther edge of the huge Bridge Fire in the Selway Bitterroot Wilderness area. It had landed there some years before I hiked in with my friend back in the 1950s and tipped over and sank in the wind. I knew it was there, and we paddled around the lake on the log raft until I saw a light patch on the bottom. I fished out a chunk of it, which turned out to be wing fabric of the plane. I may even still have the fragment, although I have no idea where. |
