Down in the swampy lowlands north of the Carlisle Institute are a few rock-on-rocks, a few ground piles with large rock components, a few rock piles on support boulders. Tim Fohl found this site and also found an interesting stone wall with a rectangular hook at one end and a curved segment at the other. It was hard to photograph. I don't have a clue what kind of site this is or what kind of piles these are, although the supported ones are pretty typical. Being mixed together this makes for a complex heterogeneous site, possibly built at different times. Examples of the ground piles with large component rocks are in the backgrounds behind the people below. Here are some of the rock piles on support boulders.See the quartz "blaze" on that last one?
Let's leave it at that. Tomorrow should be a blank and then Saturday maybe there will be more to report.
