Thanks for all the help. Looking at the wood database this wood is more likely American elm to me. The database says the heartwood is a reddish brown which matches better than hackberry. Also indicates that very young trees have very little heartwood and mostly sapwood. The end grain seems to match ( but so does hackberry). Finally it says elm is resistant to cracking and the wood was sitting in the wood pile for about a year and there is very little cracking.
