You don't have to PLAY a sympathy card for us to wish you well.
Those look for all the world like about half the wood I work with. I actually doubt you went through the first ring, since frozen under-bark wouldn't be a treat to remove, anyway. But if so, rotate the stave and see if there is a bow in another spot.
I would work down the bow to 5/8" thick limbs, leaving whatever width it gives you, then ABSOLUTELY restrain the staves to dry, like with straps or clamps. Small saplings warp in the craziest ways.
Some of the elm Siberian) that grows around here has bark just like that top one, but likely white oak. Those others I have no idea.
