I have a bunch of larger (14" - 30") diameter big leaf maple that I'd love to give away. Some of it has pretty awesome spalting. It is from a tree that fell against our house in October.
I cut it into manageable pieces, stacked it in my driveway and sealed the ends. It is way more than I can use or store. Let me know if you want to swing by take some. I live in Sylvan Highlands (west hills) near Barnes Rd and Burnside.
Here are a couple photos of pieces made from this tree.
