It's definitely up there, but Western live oak, and eucalyptus are higher in weight and BTUs. Manzanita is up there too as well as shagbark hickory. You get any of those 5 and you've got a lot of BTUs.
yup, honey lucust. Nice get. Even nicer no thorns. Ive got a cord of it CSS Summer 2020 and possibly ready for this coming season. Common yard tree here but rare scrounge for me. Love to get more if it.
