Original drilling logs

Recent well logs filed by Zielieke Well Drilling Inc., straight from the public WI DNR record:

"Records span 1948–2002" refers to the earliest and latest well logs attributed to this company in the WI DNR database — the state digitized older paper logs, so the first date is the oldest record on file, not necessarily the company's founding year.
