The two triangular ponds near the concrete structure look like they are man-made to me. But it's hard to tell since Bing only has southern facing aerials.RedRook wrote:Stream south of there is spring fed as well, and that is very interesting set of ponds. There are a ton of them sitting in that low ridge's draws (where the ridge has dips when water flows downhill). The crazy thing is that those ponds are above the creek in elevation. So they've sunk in enough to retain water uphill, and they are lined with something solid enough to keep the water there. That's a very odd combination, and it's happened multiple times.
