Unfortunately, around here the only wild, native trees are Ponderosa pine. However, the pics the OP posted look very much like my old - 30 year - cherry trees. Definitely NOT anything like the black locust planted at many homesteads around here. If you move a few feet up the trunk and find solid wood - this wood could make excellent furniture or even musical instruments. For musical instruments - hard, very tight grained wood works best. Brazilian Rosewood is one of the very best amongst the hard wood varieties. Hard, tight grained cherry can come very close to rosewood.
