PinPoint Treasure Blog

Read practical guides, case studies, legal resources, and technical tutorials covering treasure hunting, LiDAR analysis, cipher decryption, and field research.

The blog is built to help operators understand the methods behind PinPoint Treasure and apply them in real investigations.

Technical guides cover what LiDAR treasure hunting is and is not, how to read a 1-meter bare-earth hillshade without mistaking a plough scar for a foundation, how USGS 3DEP coverage is organised and where it simply does not exist, and how satellite indices such as NDVI vegetation stress and iron-oxide ratios are used as a second, independent signal rather than as confirmation of the first.

Historical guides cover the Beale cipher record and why the surveyor-chain reading of it was retracted after a Monte-Carlo control run, the documented 1889 Canyon Diablo train robbery as distinct from the undocumented 1881 stagecoach story attached to it, and the source-criticism method used across every case published here: trace a claim to its earliest surviving teller before counting any agreement as corroboration.

Practical guides cover metal detecting for beginners, VDI signal interpretation, and the legal position across federal, state, tribal, and private land in the United States. Nothing on this blog is legal advice, and land status is reported as research context rather than permission.

Every article carries the same evidence discipline as the case pages: claims are graded, coordinate precision is clamped to the grade, and negative findings are published with the same weight as positive ones.
