Survey number: 555 Event number: 19860423/21 Date: 1986-04-23 GPS: 55.21683,-6.56300. Depth: 3.5 to 0.2 m. [ View map ]

Site Description: The site is a wide tilted basalt platform covered in nodules of igneous rock the size of small boulders. The surface texture is generally rough. The seaward side of the platform is tilted higher than the landward, presenting a steep exposed edge to wave action (apart from one low mound attached to the platform but on a lower level). The platform itself is of variable height. The platform contains several types of rock pool. Because of the tilt, one large pool is filled with salt spray at the seaward edge of the platform, and delivers a sluggish seawater stream to the rear of the platform. The platform holds many wide, shallow rock pools, which tend to be under freshwater influence on the upper part of the shore. It also holds deep rock pools and large rock pools. Some of the pools are sand encrusted.
