Got a low fire on here tonight, just burning large chunks of Larch I cut and split two full years back, now very dry but retains a lot of weight, almost comparable to rock maple or oak on a piece by piece basis, good heat and lasts a long while also. Never burned it before, always left it standing but had to take down 5 large ones on a house lot, instead of tossing them on the burn pile with all the brush I loaded them in the tandem dump truck and moved them to the firewood lot. Stuff splits ok also, kept the splits just small enough to get through the door of the airtight.
