It bark and grain certainly look like it could be sassafras but that's not native to Wisconsin. Based on the fact that sassafras is an understory tree that seldom gets very large, the odds of finding a large specimen outside it's native range are low. My guess is back to burr oak. Leaves of both burr oak and sassafras are very distinctive and would help i.d. the tree.
Whatever it is, the plain sawn surface looks great, so just keep cutting it that way. If you cut it through and through and get ray fleck on the center boards, it's probably oak.
If you still can't identify the wood and really want to know, the International Wood Collectors Society probably has a member near you.
