To save you the trouble of all those different queries, just center your query at N 45 19.500, W 90 10.000. You’ll get all these areas and more. If there are certain cache types you don’t like (micros, mysteries, high terrain, high difficulty, or whatever), be sure to filter these out with your query to get more results that you would like. Note that most of the terrain 5 caches in this area are canoe/boating caches, so if you don’t want to canoe, filter down to terrain 4 or less.

Assuming you are dumping your query into GSAK, you can get this macro to determine what county a particular cache is in. The macro puts the county name in the User Data 2 field. Its a little cumbersome to get it setup the first time, but once it is done, you can use it for any US state to assign the counties. Let me know if you want a walkthrough.
