Original drilling logs
Recent well logs filed by SK Geotechnical Co., straight from the public MBMG record:
"Records span 1995–2025" 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.
