韓松洞 峰牙－己榜國(guó)家公園中的韓松洞 1991年，當(dāng)越南農(nóng)民H?Khanh偶然發(fā)現(xiàn)這個(gè)洞穴韓松洞時(shí)，很快就可以看到這個(gè)張開的嘴通向一個(gè)巨大的、黑暗的、未被觸及的空間，里面有一條自由流動(dòng)的地下河。他當(dāng)時(shí)不清楚的是，這個(gè)現(xiàn)在被稱為韓松洞的洞穴是迄今為止世界上最大的洞穴，音量不足為了進(jìn)一步探索洞穴，康只能回到家里，告訴朋友他的發(fā)現(xiàn)。但他無法回到山洞，他的足跡被叢林吞沒。由于流言傳聞，這個(gè)洞穴幾乎20年未被探索，直到一個(gè)英國(guó)洞穴探險(xiǎn)者的訪問團(tuán)隊(duì)聞到了康的故事。2009年，Khanh帶領(lǐng)他們經(jīng)過長(zhǎng)時(shí)間的搜尋，來到了韓松洞，開始了探索，發(fā)現(xiàn)洞穴的面積超出了任何人的預(yù)期。韓松洞的體積超過15億立方英尺，主室高650英尺，寬近500英尺，綿延超過3英里，大到可以讓一架波音747飛機(jī)飛過去，但要小心為了15層的石筍。洞穴中有一個(gè)巨大的洞穴，像這里看到的那樣，有一個(gè)巨大的凹陷，陽光暴曬的部分，擁有一個(gè)完整的雨林生態(tài)系統(tǒng)。而這正是我們目前所知道的：洞穴潛水員還沒有完全探索韓松洞的地下河，而最近在2019年發(fā)現(xiàn)的大量通道只增加了人們對(duì)洞穴的巨大了解。

原文:

When Vietnamese farmer H? Khanh stumbled upon this cave in 1991, it was immediately clear the gaping mouth led to a huge, dark, untouched chamber, complete with a free-flowing underground river. What couldn't have been clear to him then was that this cave, now known as S?n ?oòng, is by far the world's largest in volume.Lacking gear to explore the cave further, Khanh could only wander back home and tell friends about his discovery. But he was unable to retrace his steps to the cavern, his tracks engulfed by the jungle. Relegated to rumor, the cave went unexplored for almost two decades until a visiting team of British cavers caught wind of Khanh's tale. In 2009, Khanh led them to S?n ?oòng after a long search, and explorations commenced that found the cave was vast beyond anyone's expectations.S?n ?oòng is over 1.5 billion cubic feet in volume, with its main chamber 650 feet high, almost 500 feet wide, and stretching more than 3 miles, large enough to fly a Boeing 747 through—but look out for the 15-story stalagmites. One of the cave's massive dolines—sunken, sun-exposed sections like the one seen here—hosts an entire rainforest ecosystem. And that's just what we know so far: Cave divers have yet to fully explore S?n ?oòng's subterranean river, and vast passages found as recently as 2019 have only added to what's known of the cave's enormity.
