Any idea what this is?

Sorry I pretty sure the 198% is wrong, including me, don't think it's Hickory now, looks like some kind of maple maybe. Pappy

Pappy I think you're dead on. That's why I asked for edge grain because I suspected it was a diffuse porous wood from he end grain shot.

Only maple (and maybe sycamore) looks like that in edge grain.

Couple more shots in bright light, in case it makes a difference, since I peeled off the outer and inner bark.

I'm thinking a maple also, now.   In the last pic it looks powdery on the back. If that is the case it means fungi has infected it.

On more, and then I'll stop cluttering the board with pics, for now. After I finished peeling all of the pieces, I noticed an interesting rippled pattern on the back.

Sorry about the lighting. I'm afraid it made the picture a little... grainy.

I did use some 240 grit sandpaper to get the last little bits of inner bark off, so that may just be sandpaper dust.
