Volcanoes by the Sea: A Geology Tour of North Berwick with @ScottishGeologist

Join @ScottishGeologist on a coastal geology tour of North Berwick, where ancient volcanoes meet sandy beaches and tidal platforms reveal a dramatic geological past. With views to Bass Rock and the Firth of Forth, this accessible field trip brings to life the Carboniferous volcanic landscape of East Lothian — once home to lava lakes, tropical swamps, and shallow seas.

What to Expect

🌋 Explore a Volcanic Past

  • Walk across the eroded remains of a Carboniferous volcano, with excellent exposures of basaltic lava, volcaniclastic rocks, and tuffs.

  • Learn how North Berwick Law, Bass Rock, and Craigleith are all volcanic plugs — the solidified centres of ancient volcanoes that once dominated the region ~340 million years ago.

  • Identify classic features of igneous intrusions, including columnar jointing, baked contacts, and chilled margins.

🪨 Sedimentary Layers and Fossils

  • See interbedded sandstones, mudstones, and limestones along the coastline — deposited in ancient estuaries, lagoons, and shallow tropical seas.

  • Look for fossils of marine life, such as brachiopods, crinoids, and corals, in weathered limestone blocks and loose material.

  • Learn how the landscape alternated between volcanic eruptions and quiet marine deposition.

🌊 Dynamic Coastal Features

  • Explore tidal platforms, wave-cut benches, and sea stacks, where erosion exposes some of the best rock outcrops in East Lothian.

  • Observe how modern processes like wave erosion continue to shape the rocks and sediment today.

  • Discover how geology influences the layout of the coastline, harbours, and natural defences.

🧭 Iconic Viewpoints and Landforms

  • Get panoramic views of Bass Rock — a volcanic plug now home to thousands of seabirds — and learn about its geology and history.

  • See how local landforms like The Law, Craigleith, and Fidra are all geologically connected.

  • Understand how volcanic activity in the Carboniferous created the chain of plugs stretching across the Firth of Forth.

👣 Hands-On Exploration

  • Try identifying igneous textures (fine- vs coarse-grained), sedimentary bedding, and fossils in the field.

  • Use simple tools (like hand lenses) to interpret rock relationships and discuss how geologists reconstruct past environments.

  • Enjoy interactive discussions on how volcanism, sedimentation, and sea-level changes all left their mark on North Berwick’s rocks.

Who Should Attend?

  • Great for beginners, families, students, and geology enthusiasts of all levels.

  • Especially suited to those interested in volcanology, fossils, and Scottish coastal geology.

  • The route is mostly flat and walkable, with optional rocky shore sections depending on tides.
