Original drilling logs

Recent well logs filed by Montana Highway Dept., straight from the public MBMG record:

"Records span 1965–2019" refers to the earliest and latest well logs attributed to this company in the MBMG database — the state digitized older paper logs, so the first date is the oldest record on file, not necessarily the company's founding year.
