Yorktown (12/23/2014)

It is really nice to be outside in the woods early in the morning after a day of rain or when it is foggy.  Today it was both.  All the trees were still damp, which makes the bark turn really dark and makes the lichen and moss stand out.

Lichen are very interesting organisms.  They actually are a symbiotic relationship ship (you scratch my back and I'll scratch yours) of algae, bacteria and fungi.  Somehow by living together they are able to create these wonderfully colored structures that live on rock, and in our woods on the trunks of trees.  This symbiotic relationship makes them strong and able to live under very harsh conditions.  Typically they live on the northern sides of trees and rocks, where they are not baked by the sun.

Here is a picture I took today during my walk this morning.  It was great to be out in the woods again.  Life is still dry, the ponds have no or very little water in them; but regardless it is so enjoyable walking in the woods.  Foggy day walks are my favorite.
