I have been saving crotch logs that I get that are normally left in the woods during commercial logging operations. I am always amazed how much material is left in the woods but I understand the economics of that decision. I always try to save them when I find them as they make great door panels, box tops, display bases, or turning stock. I had several walnut and cherry ones that i decide now was a good time to cut them up. They can be a challenge to get securely dogged in the mill but the effort i think is worth it. I usually cut them 2" thick so they can be resawn and book-matched if desired.
