So, I found some very dead wood that I bucked in the woods. It measures below 25% when I split it yesterday - some even 13%. Hardly any of it is punky and/or soft as it fell onto other trees and was off the ground. I have no clue what it is, however it has a very strong oder once I brought a few pieces into the garage. It's almost like a strong rubber or chemical smell. I can't place it at all.
