Original drilling logs

Recent well logs filed by Mountain Research LLC, straight from the public DCNR record:

"Records span 2003–2025" refers to the earliest and latest well logs attributed to this company in the DCNR database — the state digitized older paper logs, so the first date is the oldest record on file, not necessarily the company's founding year.
