Were you trying to post photos?  I was curious to see your find.  I don't see any photos in your posting, though.

Somehow I thought I had added a couple of pictures. I will try it again. I see I get an error about the file size. So I will have to resize them and try again tomorrow.

Interesting find Paul. 3.4 miles is a lot of trail, and looks like a lot of elevation gain. Hope to see the photos.
