Here it is in spring 2015.
In 2015 I noticed the bark beginning to buckle. This spring, 2016, that bark had flaked off enough to reveal some deadwood.
I began to use a chisel to lift the bark that was obviously coming off. The proceeded to use the chisel to discover the live vein.
This was all that was deadwood. I'll use my dremel along the grain of the wood to eliminate the tool marks. As the deadwood dries and the grains crack it will be easier to look at!!
Here is the tree at this point.
