Lost Blue Hole

East of Nassau, a near-perfect circle about thirty meters across opens in the sand at twelve meters and drops far beyond recreational range. The rim is the dive: coral heads ring the edge like a crown, nurse sharks stack up in the hollows, sometimes half a dozen deep, and schools of jacks and snappers rotate above the void. Divers typically circle the lip, drop a short way into the shaft to feel its scale, then return to the rim's fish traffic. Summer aggregations inside the hole can be dense enough to dim the light below.

Momen yang Anda nantikan: Sheer-sided ocean blue hole, piles of nurse sharks on the rim

Topografi: Sand plain broken by a coral-rimmed circular shaft

Bahaya: The shaft invites uncontrolled depth; set limits before descending and watch gauges against the featureless walls.

Nitrox: Worthit di sini: profil berada dalam kisaran di mana enriched air secara berarti memperpanjang waktu no-stop (dengan pelatihan untuk menggunakannya).
