Walking in the woods and looking at trees generally involves a lot of looking up but not seeing much detail from my ground-bound viewpoint. Sometimes, though, the detail is not "up there" but down where it comes into clear view. The lichen on this oak trunk was right at eye level, so I was able to study and capture it on camera. It does appear that the bark is dotted with "little gray beards".
Thoughts on the park, its residents and how to preserve its natural beauty.
