Original drilling logs

Recent well logs filed by Montana Salinity Control Association, straight from the public MBMG record:

"Records span 1954–2026" 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.
