I don't know about any elms that might be native to that region, but the elm here in New England...well, the proof is in the splitting. Buck up a round and whack with a maul. Damn twisty-stringy grain makes it quite the chore to split.
Yep on the splitting PITA for elm, but great for woodburning!
Like PB said, I know that a lot of elms were planted as ornamentals for a long time before Dutch Elm got them back in the 50s and 60s. Possibly that tree was a hold out because elm is not native for that region or there are some dutch elm reisistant strains. Dutch elm does not kill the tree every time either. I cut about a dozen last fall that had finally succumed to DED that were 36-48" DBH range. They showed signs of earlier attacks and healing.
