I wish I'd gotten a better shot of this, it's(to me at least) one of the most interesting details in the house. It's the intersection of the 6/12 kitchen.dining ceiling with the 10/12 vault over the great room. The 4x10 bastard valley is supported on a 6x12 beam at the bottom and carried with lag bolts off a 4x12 shop-built truss at the upper end. There's a 2' difference in wall heights so we couldn't simply run the valley to the back wall and we really didn't want a long interior wall to support it that would interfere with the flow at the floor level. So we stuck a 6x12 on top of the wall and landed the valley on that. It really opens up both rooms.
