Guys I thought it was Spalted as well. But I got these boards the week the logger cut them green and he he said that it was kike that in that batch of trees. If you see it up close and cut into it you will see that it is probably not Spalting. It is verigated grain color....may be some type of spalting not really sure. I know some of it is absolutly beautiful!
Very hard for poplar!
