This excursion will examine the coastal rock sequences from the East Beach Dunbar to Belhaven Bay. We will encounter Devonian and Lower Carboniferous sedimentary rocks, and a range of extrusive and intrusive igneous rocks. We will see evidence for arid conditions and early land plants as well as lagoonal deposits of warmer times. The igneous rocks offer an array of field relations and textures from dykes to major vent structures. Several major faults are crossed, with a textbook example of a fault scarp. Note there is no coach for this excursion: travel to Dunbar by public transport or private car, meet in Dunbar at 10.30 am.

Terrain, walking distance, height gain:

Total distance will be about 6km (including return walk). This is a coastal walk, so there is little height gain, although some flights of steps are encountered.

We will be walking on slippery rocks of the intertidal zone at times and along rough tracks at others.

Specific or Medium- / High-Risk Hazards:

Tides, slippery rocks of the intertidal zone.

Control measures required to mitigate against any Hazards referred to above:
