Yes it is a Tulip Poplar and is the Indiana State tree. They also call
it a YELLOW poplar because when you saw the lumber it has a yellow tent
to it. Our ancestors love this tree because termites won't mess with it.
They sided their barns with it and unpainted it would last 100 years. It
is not real hard but great for framing. My house is framed complete with
it. I also paneled some rooms with it. when exposed to the light it
turns a soft brown and after several years it is hard to tell from
walnut.
