The Woodpile

I was pulling into a parking spot behind the planetarium tonight, before my astronomy meeting, and I saw this.  There is a woodpile there, made up of wood from trees cut down on the property.  I think they use the firewood for the fireplaces in the Vanderbilt Mansion, for some of the programs they have for visitors.  Anyhow, I was stunned by the condition of this section of a tree trunk.  It looks as if it has been half eaten by some kind of worms.  I think the photograph is also about the design of the elements within the frame.
