Evidence journal
Plain-language guides to source quality, location precision, uncertainty and the publication decisions behind the atlas.
Each article is structured, source-linked and reviewed against the same safety rules as the map records.
Ground-penetrating radar has been used on the Isle of Man, and this atlas publishes nine named survey contexts. A circle is a public context, not the working grid. An anomaly is a change in the radar return, not an artefact, a grave or a reason to disturb the ground.
Read the evidence guideDeclared treasure on the Isle of Man is a legal outcome, decided by the Coroner of Inquests after a find is reported to Manx National Heritage. The announcements name the finder and the object. They deliberately do not name the field.
Read the evidence guideVisit Isle of Man says the Island has 26 official dark-sky sites, and its autumn and winter notes name a handful of horizons. The browsable list checked the same day had 25 cards. A card is not a night-time ticket, a path or a pin.
Read the evidence guideOctober still sits inside the published 2026 season for Manx National Heritage's ticketed sites. November mostly does not. Hop-tu-Naa falls on 31 October, and live listings, not this journal, carry the hours and prices.
Read the evidence guideAfter Sunday 1 November 2026 the published season for Manx National Heritage's ticketed outdoor sites is over. Two buildings stay on a daily winter clock, and both close on Christmas Day, Boxing Day and New Year's Day.
Read the evidence guideThe Way of the Gull is the Isle of Man coastal path, and official pages do not agree on a single mileage. This autumn guide covers the published lengths, the four government sections, tides, rights of way and coastal monuments.
Read the evidence guideRecord parish, path type, fingerpost wording and open questions. Keep folklore as questions until you have a named source — never invent tide times or difficulty grades.
Read the evidence guideFolklore can be culturally real without earning a public map pin. Manx Treasure Map keeps story tone separate from geometry so readers do not treat a tale as a dig brief.
Read the evidence guideCoastal wreck pages and inland place pages answer different evidence questions. Read wreck geometry as approximate maritime context, inland markers as public-feature references, and never treat either card as permission to dive, detect or excavate.
Read the evidence guideA Manx Treasure Map place page is an evidence summary, not permission to dig, metal-detect or visit private land. Read the marker type, the named sources and any withheld-location note before treating a point as something you can act on.
Read the evidence guideThe map uses four location treatments because source identity, coordinate precision, public safety and legal access are different questions. This guide shows how to read each treatment without turning an evidence record into a search instruction.
