I've been out scrounging for dead wood, and found some nice long dead, laying on the ground, red oak with the inner bark crumbling away. The wood looked great, however after splitting I noticed light oval colored spots scattered along the grain. When burning it seemed punky, and wanted more air to burn. With small splits, like 2x3 inches, it seemed to get past the punkiness and burned ok. I do not know what the moisture content is. Are the light spots a sign of bad wood and an early sign of decay? Is the wood salvageable, or relegate it to the outdoor fire pit?
Both pictures are of the same split, with one pic zoomed in.
