nw/nc iowa on the banks of West Buttrick Creek..
Neighbor said he worked on them as a young guy, he is 92 now. I find them amazingly accurate on our farms here in NC Iowa. Especially good on the high lime spots, even small areas. Will ask him next time I see him, as far as when they were done.
Where did soil survey maps come from?
