Yonaguni Monument
Depth साइट की ऊपरी सीमा से उसके सामान्य maximum तक की range है; "recommended cert" वह mainstream-agency level है जो operators आमतौर पर माँगते हैं, कोई कानूनी नियम नहीं। Currents और visibility रोज़ बदलती है, इसलिए सब कुछ planning ranges मानें।
The Monument is a mass of layered sandstone the size of a building, cut into flat terraces, straight edges, and stark right angles, found in 1986 by local diver Kihachiro Aratake while scouting hammerhead grounds. Whether people shaped it is a genuine, unresolved argument. Marine geologist Masaaki Kimura spent years cataloguing what he interpreted as tool marks, drainage channels, and even carvings; most geologists respond that this sandstone naturally fractures along horizontal bedding and vertical joints, producing staircase forms without any hands involved, and that similar geometry appears on the island's shoreline. Diving it, you sweep across the main terrace, duck the surge behind the prow-like corner, and understand why both camps sound so sure of themselves.
वह पल जिसके लिए आप आते हैं: The terraces and right angles themselves, the natural-versus-carved debate, big Kuroshio visibility
टोपोग्राफी: Massive stepped sandstone formation rising from about 26 m toward the surface
करंट: Kuroshio-driven flow and surge over the terraces are routine; calm days are the exception to plan for.
प्रवेश: Short boat runs from the island's harbors; entries are timed around surge and the current wrapping the south coast.
पानी में उतरने से पहले जान लें
खतरे: Surge over the terraces, current at the corners, and swell surface intervals; listen hard to the local briefing.
Nitrox: यहाँ उपयोगी: प्रोफ़ाइलें उस रेंज में हैं जहाँ enriched air no-stop time को सार्थक रूप से बढ़ाता है (इसके उपयोग के प्रशिक्षण के साथ)।
