How PinPoint Treasure applies to Montana: our AI research companion cross-references historical archives, geological data, mining records, and 1-meter LiDAR terrain scans to narrow productive ground in Montana to GPS-tagged candidate coordinates before any field work begins.

Recommended workflow for Montana: start with the historical case that interests you, use the cipher engine on any period notes, run a LiDAR scan on the resulting bounding box, and cross-check anomalies against NDVI and iron-oxide satellite signatures.

Legal reminder: pre-1900 archaeological resources on federal land in Montana are protected by the Archaeological Resources Protection Act (ARPA); always confirm land status and carry written landowner consent on private ground.
