- This root is preserved as an internal mould, in a tough sandstone.
- The path is waymarked throughout its length and for the most part sticks to the coast, running over the chalk and sandstone cliffs which characterise the island.

- The start of a prominent band of energy at close to 1.0 second at Larne-2 ties with the top of the Lower Permian Sandstone and the thin overlying Magnesian Limestone in the well; the two horizons are too close to be separated seismically.
