Fairly high profile corestone reef around the pinnacle, and another large outcrop some way to the east. Quite pretty. Typical medium depth west False Bay invertebrate cover, with lots of sea fans.
This site is in a Marine Protected Area (2004). A permit is required. The site is entirely within the Boulders Restricted Zone of the Table Mountain National Park MPA.
The name "Livingstone Reef" is derived from the name of the diver who found the pinnacle by accident when diving the north pinnacle of Castor Reef. The reef was known to exist, but had not been reported before as a dive site.
Maximum depth is about 23m on the sand and the top of the pinnacle is about 14m. There is another pinnacle to the east which comes up to about 15 or 16m.
The pinnacle is fairly compact, but made up from a group of large rocks clustered together with crevices, gaps, and a few overhangs. The highest rock extends about a metre above the 15m depth, and the local area is generally above 18m for several metres around.
The surrounding reef is relatively low, mostly between 21 and 18m deep, and the sand is at about 23m.
The reef is elongated from north-west to south-east. The length is estimated at about 250m, and width fron south west to north east is about 30m near the pinnacle. The pinnacle slopes down rapidly to sand to the north-east and southwest, while to the south-east and north west the slope is more gradual, over quite an area of low reef. Further to the south-east it gets more rugged again, and to the north-east more reef is visible a few metres away across the sand.
About 100m to the south-east of the pinnacle there is another slightly lower monolithic pinnacle reaching up to about 16m depth from the sand on the north eastern side. This area has not yet been mapped.
Geology: Granite corestones of the Peninsula pluton, surrounded by fairly fine quartz sand.
The site is exposed to south easterly wind and waves, so should be dived in light winds, or if the wind is somewhat from the west, and is often good in winter. The site is reasonably protected from south westerly swell, but if the wave period is long there may be significant surge. This is an area which sometimes has a thermocline, and the temperature may drop several degrees, often with a marked improvement in visibility, resulting in better but colder conditions than the surface would suggest. Temperatures may drop by more than 5%deg;C across the thermocline, and this is more likely in summer.
Boat dive: The site is too far offshore to swim
