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.

Khoảnh khắc bạn đến vì nó: Swirling jack and baitfish schools, eagle rays on the current line, outside chance of a whale shark.

Địa hình: An isolated coral seamount rising from deep water to within about 12 m of the surface.

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

Điểm vào: Open-water buoy southeast of the island; descend the line — there is no other reference.

Nguy hiểm cần lưu ý: Open-water current and no bottom reference off the mount; keep the summit in sight and ascend on the line.

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

Nitrox: Đáng dùng ở đây — các hồ sơ nằm trong khoảng độ sâu mà nitrox có thể kéo dài thời gian không dừng một cách thực sự có ý nghĩa (khi đã được đào tạo sử dụng).
