The dark area you see near the lower middle of the picture shows charcoal. This was an old growth stump that had been charred as the fire went through. A seedling sprouted on one side of the old stump and began growing.
Now about 75 years old, the seedling is over 100 feet tall and all but enveloped the old, burnt stump that is nourishing its growth. On the picture, the right side of the stump is all bark from the grown seedling.
This tree will have to be cut off above the old stump in order to be felled. That means the undercut and the falling cut will be about 8 feet off the ground.
