Looks like you have a mix. The top three pictures look to be maple (or something close) and the bottom three look like oak.

Maple has a very weak grain and (in my experience) spalts easily if left outdoors. That endgrain shot looks very pore-y, which would be indicative of oak. That and it seems to have some ray fleck, which is also an oak characteristic.

I’d wait until the experts weigh in, though.
