Trees

When our tour guide told us that there was a layer of sandstone under us, I figured that the trees would have some above ground roots. This normally happens when the trees have damp feet. Given that he also told us that there were no above ground streams because everything filtered through so quickly, I revised my hypothesis and decided that there would not be. I was half right. There are some above ground roots, but not many. Here are some.
I noticed that there were no beech trees. It always amazes me at the history of this area and the assertation that, yes, there was farming going on where the park area now is because I know that the soil here is thin and rocky. How do I know this? Well, I can see it and I notice no beech trees. Even early settlers knew that where the beech grew the soil was deep and rich. Why someone would settle here with no above ground water, thin soil and difficult terrain to boot is beyond me.
