  1. 1
    Records research (FS 3.A)

  2. 2
    Field investigation
    Find original monuments. Note their condition, type, witness evidence. Photograph.

    Senior rights, intent, natural monuments, artificial monuments, adjoiners, courses, distances, area.
  4. 4

Concepts that show up on the exam

Boundary determination
The professional decision about where the boundary lies. Documented; defensible; signed.
Pincushion
When successive surveyors set their own monuments at one corner, accumulating the disagreement. Should be resolved by determining the controlling monument.
Original measurement accuracy
1880 chain measurements were 1:500 to 1:5,000 — much less precise than modern. Don't hold the record bearings/distances over original monuments.
Controlling monument
The single monument that controls a corner when conflicts exist. Determined by senior rights + evidence hierarchy + professional judgment.
