We have mostly piñon at our place, with some scrub oak, ponderosa and Douglas fir.
The Utah firewood chart ranks the piñon at 27.1 million BTU which is pretty good. It’s very fragrant with sticky sap. I’ve found it burns the best with very little creosote buildup if I let it dry for two years (if cut down while green) or one year (if dead when cut down).
