Now, now. I'm not BSing you. There are at least six abandoned home-sites in this image. Let me show you.
This is a rock ring for a Costanoan house. You still drop a foot or two below the surface of the hill when you step inside. It might have looked like this below when it was first built.
What's neat is that you can still see the entrance where the rock circle is interrupted in 2. It matches the entrance depicted in 3.
Cool O.G.S., so you found ONE rock ring. You said this was a neighborhood. Lame. Well, the grass was really tall and it was darn near impossible to make out anymore dwellings while I was up there. Here's a great aerial image from when the cattle grazed everything down so you can make out more dwellings.
You can make out several dwellings' worth of rock circle foundations here. They were laid out almost in an L-shape probably as a wind block.
What's most interesting about thia site is that it is on top of a hill. Most native California sites like this are near water sources. There is a creek at the bottom of this hill but it's quite a far walking distance. I suspect that this was a defensive position. From here you can see trouble coming from far away. Perhaps this group of natives was harassed by settlers and decided to move to the top of this hill for safety. We'll never know.
Later settlers to this hilltop put up a redwood and barbed-wire fence. Kinda neat that there are artifacts from two completely difference people at two completely different times in history at the same place.
think this is cool. Some of you are bound to think so as well. Sure, it was a little click-baity but it truly was a neighborhood at one time.
Just some bonus shots:
