Well blow me down... Thats persimmon?!?! I had cut a piece once thinking it was dog wood. Exact same bark and black wood in spots like yours shows. That bow I made was one heck of a bow. And let me tell you, heat treating it over a camp fire did wonders to it. I have another bit of wood cut 2 years ago, probably going to turn it into a bow fishing rig. Good luck with the wood! Thats good stuff from my experiance.
