Found what appears to be a piece of a branch Sunday, May 19th at the entrance to the path around Lake Churchill in Germantown, MD. Montgomery Co. There are a ton of trees around the lake, but not any immediately above where this is located, which is very near the path as you emerge from the tunnel at the south entrance. It has a circumference of about 6 inches. There was a small tree branch that had fallen onto the path several hundred yards away. It's possible both were brought down by a storm. That appears to be a normal Oak Tree. What struck me was the interior of the branch in the picture. It looks as orange as it seems in the picture. Is there a tree (or large bush) in the area that has orange interior bark - or possibly a root? If not, is this some kind of disease or evidence of human tampering. As I was cropping the picture I noticed there is above it another piece of wood that might be part of the same tree branch. I didn't notice it at the time and have no idea what color the phloem is. Curious, but obviously if it's a disease, would appreciate knowing. Thanks, Ileana
