Black Hills

Black Hills is Utila's fish magnet: a lone coral hill in open water that everything passing must visit. Circling the summit feels like holding a busy intersection: horse-eye jacks wheel in silver carousels, great barracuda hang nose to current, snapper and grunt schools drape the slopes, and spotted eagle rays climb the up-current face. The site's blue-water position gives it the island's best odds, after the boat rides themselves, of a whale shark ghosting past mid-dive. Navigation is simple (it is a hill), but the surrounding bottomlessness keeps the dive honest.

您此行的高光时刻: Swirling jack and baitfish schools, eagle rays on the current line, outside chance of a whale shark.

地形地貌: An isolated coral seamount rising from deep water to within about 12 m of the surface.

水流: Exposed to whatever the open sea is doing; some days still, some days a flagpole.

入水方式: Open-water buoy southeast of the island; descend the line: there is no other reference.

危险因素: Open-water current and no bottom reference off the mount; keep the summit in sight and ascend on the line.

保育: An aggregation point that concentrates spawning-size fish; the no-take ethic matters doubly here.

高氧（Nitrox）: 在此值得使用：这些潜点的深度范围内，富氧空气（nitrox）能有效延长免减压停留时间，前提是您已接受相关培训。
