Tim M. commented about the stone wall that is part of the the stone wall bulge in a prior post. Click here for the link to the 2/29/08 post and comments.
I went back to the wall yesterday for some more photos and found a few more things that I hadn't seen before.
Here is one picture of the wall bulge, that I took last fall:
Not far from the wall bulge is this stone, resting rather inconspicuously on the wall, semi upright. I hadn't noticed it before. If you click on the image to enlarge it, you may be able to see a mark on the stone, near the center, like an upside down L. There are two similar marks in the lower left hand corner of the stone, running up and down. I don't know if these marks are natural or not.
I also noticed a couple of breaks in the wall that I hadn't paid attention to in the past. After a small break in the wall that is connected to the wall bulge, there is another stone, this one standing against the wall, not on top:
Then there is an aperture in the wall. This aperture is not far from one of the rock piles in the large cairn field:
Right next to the aperture, there is this unusual set of structures:
There is an unusual rock, which I believe is a quartz conglomerate, there, right next to the bright green mossy area. Here are some close ups:
I was convinced before that this is not a colonial or agrarian stone wall, but now I am certain.
