So cut some? And dry it bark on ?

There are some thicker ones in that stand.

For me, Ironwood is Olneya tesota (Sonoran desert) is one of the heaviest, densest woods in North America. It sinks in water, and a chunk of it in my wood burning stove will last 18 hours. I got a bunch of it from a guy who was selling his house, he cut down a bunch in the 1960's. That stuff will eat a chainsaw blade in a matter of seconds.
