YONDERLODE FIELD NOTE · MAP READING
Read the ground before you plan the trip
A concise guide to reading Yonderlode’s planned map layers: use geology for context, boundaries for questions, and historic finds as clues that still need checking on the ground.

1. Start with geology as context
Geology can help you understand why a place is worth investigating, but a coloured unit or boundary is not a promise of gold at a particular spot.
- Read the legend, map scale, source date, and mapping resolution before interpreting a colour or line. Regional geology is useful context and may not describe every outcrop.
- Look for relationships between mapped rock units, contacts, structures, and drainage as hypotheses to investigate—not as proof of a recoverable find.
- Keep the map view broad first, then compare it with current imagery, terrain, and any field observations you can lawfully make.

2. Treat tenement boundaries as a permissions check
A boundary tells you that a tenure or land-management question exists. It does not tell you that entry or prospecting is allowed.
- Check which state or territory authority maintains the current tenure record, and confirm the record’s date and status before relying on it.
- Separate mining tenure from land access. National parks, reserves, private land, pastoral leases, Indigenous land, roads, waterways, and other areas can have different requirements.
- Contact the relevant authority and landholder where required. Do not cross a boundary, prospect, or camp because the map appears open or unmarked.
3. Use historic finds as clues, not evidence
Historic markers can show where earlier records exist, but they vary in accuracy, age, source quality, and legal relevance.
- Check what a find record actually represents: a reported occurrence, a worked site, a specimen, or a general locality. Do not treat every marker as a precise coordinates-level result.
- Compare the record with its source, date, scale, and surrounding geology. Several nearby records may reflect one historic locality rather than several independent targets.
- Use old finds to form a shortlist for lawful research, then verify current conditions, access, and any restrictions before making a trip plan.

4. Finish with a field-planning check
A responsible plan connects the map to current official information and permission for the specific location.
- Record the layer names, source dates, and coordinates you used so you can re-check them if the trip changes.
- Confirm current access rules and permissions with the relevant state or territory authority, reserve manager, and landholder before departure.
- Carry the conditions of any permission with you, respect closures and cultural or environmental protections, and turn back when access is uncertain.
