Whittle rock and surrounds

This is said to be a pleasant dive on a small but pretty reef, with enough area above 40 m to be worth diving on nitrox, and a fair amount of deeper reef along the sides.

Position

1 Sandy-top Ridge S34°15.153' E18°34.709'

Reef dive, boat access only. East of Whittle Rock and South of Bruce's Mark. A smallish granite outcrop rising from about 47 m on the sand to about 32 m deep at the flattish top, which has a sandy depression at the south end of the high reef. This site is not in a Marine Protected Area. A permit is not required.

Name

The name "Sandy-topped Reef" is descriptive of the unusual sand patch in a depression on top of the reef, about 10 m above the surrounding sand.

Depth

Maximum depth is about (depth) m. and the top of the reef is about (depth) m. Quite a large area is above 35 m. Average depth of a dive is likely to be about 40 m.

Topography

The reef is a large granite outcrop with large boulders along the sides. The long axis is northwest-southeast, similar to other reefs in the vicinity. It is relatively long and narrow, with two areas of relatively high reef. The main area is to the northwest, where the top of the reef is at about 32m, and there is a depression or gully between the sides where sand has accumulated at about 36m depth, with ridges to both sides a few metres higher. The sand bottom around the reef is significantly deeper, at about 48m to the east. The east and south sides of this part of the reef have large chunky boulders, with deep cracks, crevices and some overhangs, and the top is more rounded and split by long cracks. Most of the reef remains unexplored. The southern section is deeper. The ridge tapers away gradually to the northwest and more bluntly to the southeast. Length is about 400?m and width about 80?m across the northwest section of high reef.

Geology: Pre-Cambrian granite of the Peninsula pluton.
