Parchmarks in the park

I've been watching these parchmarks develop in Pilrig Park over the last few weeks. I noted them a couple of years ago and now they're showing really clearly. They relate to a couple of paths that I've found on late 19th and early 20th century maps, as well as the wall following the main drive up to Pilrig House (in the extra). It's nice to have a little bit of archaeology in your local park!
