Hi All:

We were in the woods today and came across this dead tree with unusual
horizontal lines on it, which covered the entire trunk from top to
bottom.  I wonder if someone can tell me exactly what made these lines
on a dead tree, or perhaps they were what killed the tree in the first
place.  There is a single "bore" hole near most of the horizontal
lines.  I was wondering if this could be the handiwork of a spruce
budworm or something similar?  The second picture shows the single
hole next to the lines better.  There is also a raised squiggly
vertical line - wondering what this is too.  Thanks for any help.
