Does butternut also have those chambers? I have a thread here looking to identify something in the walnut family that I was pretty sure was not black walnut (wrong bark). Not mentioned there is that the couple twigs I had did have the chambers. It dried pretty quick and pretty light, so I went with butternut. Whatever it was, it looked nothing like the wood in this thread.
Edit: just googled, it does. But I also found a site that shows butternut wood with no color difference between heartwood and sapwood: http://www.dnr.state.oh.us/forestry/trees/butternut/tabid/5347/Default.aspx
