  "summary": "A high, surprisingly level headland records an ancient marine erosion surface that local geological interpretation describes as a largely submerged warm-water reef around 10 million years ago.",
  "editorialInterpretation": "Pleinmont compresses several geological timescales into one walk: ancient metasediments and granite form the headland, later seas planed its upper surface, and much younger coastal erosion cut the cliffs seen today. The published coordinate is a safe trail-access reference on National Trust land, not a fossil collecting point.",
