Original drilling logs
Recent well logs filed by Lang Well Drilling Co. Inc., straight from the public WI DNR record:
"Records span 1985–2022" 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.
