RedBud maybeThat looks a lot like redbud, or as I call it to my wife's chagrin, "golden oak". We had one of those come down during last year's ice storm and the yellow wood looks a lot like my former tree. The giveaway for redbud though is that the fibres of the wood kind of twist around as the tree grows upwards, giving the wood a lot of strength and making it a pain in the *** to cut or trim. I took a close look at the bark in your photos and it looks like that too. There should be a reddish hue to the bark, but I can't make it out from the pictures.
