Going to the dump. Why ? What else would I do with it ?
A lot of it depends on what you have for tools/equipment. And if you have any interest in woodworking, or know someone that is. When you cut that into slabs from top to bottom you will find some interesting grain lines. It would take a least a year to dry it for woodworking after it was cut up. Some wood turnings will turn in wet as it is easier. But they can only get close to the final pattern, then it needs to be dried. There is a process to that. I don't have the equipment needed to slab it though.
