About Unnamed Reef

This site is situated just past Army Beach and around the corner from Ka'ena Point and can be found about half a mile offshore - it has yet to acquire a name! This unnamed reef is a sequence of ledges which runs perpendicular to the shore and is interspersed by channels of sand. This cluster of caverns (at a depth of about 60 to 70 feet) houses a diverse selection of crustaceans and shells, including triton's trumpet. One should be cautious when viewing tritons as they are always surrounded by a group of poisonous crown-of-thorns starfish. There have been several sightings of whitetip and blacktip sharks. Be aware that this dive is for experienced divers only and that the site is usually inaccessible during winter months.

Dive Site Hazards

Bubble Trapping Under Overhangs — Rock overhangs can trap exhaled bubbles, reducing visibility and causing disorientation.
Reflected Surge Patterns — Surge reflecting off rock faces can create irregular and unpredictable water movement.
Current Funnel Effect — Narrow gaps between rocks can accelerate water flow unexpectedly.

Hidden Depth Variations — Complex reef topography can conceal depth changes, leading to unintended profile variations.

Distraction from Marine Activity — High fish activity can distract divers and delay depth or gas awareness.

Rapid Surge Direction Changes — Surge near reef structures can reverse direction quickly, pushing divers sideways into unexpected areas.
