The local legend
Palawan Islands is well known for the capital Puerto Princesa , green city , Philippines cleanest , have 2/3 of the area is covered with forests . It has a national park famous Puerto Princesa Subterranean River , located in the mountains northwest of St. Paul Island .
Garden Puerto Princesa Subterranean River National UNESCO World Heritage Site in 1999 , is home to conserve biodiversity mountain ecosystems - the most important of the Philippine Sea . The most special thing is the park's spectacular limestone scenery , long underground river system and extensive underground cave . Underground river originates from the mountains of St. Paul , at an altitude of 100 m , 8.2 km underground before flowing into the sea .
People in Palawan always persuade tourists to visit the underground river close with stories and real life , closely associated with the religion of this island nation . A round trip of more than 2 km long cave segment lasted like 45 minutes conversation with God . Since the formation of the arches , columns , cliffs , stalactites and stalagmites and natural colors create a lot of religious imagery in the Bible , like Mary, Jesus Christ's face , holy family , angels , three kings and welcome Baby Jesus candle . Arch cave is like the dome of the church with many niches cave 60 meters high , 120 meters wide .
The giant stone pillars like the fortress of ancient civilizations . The big mushroom columns , shaped as eagles animals , chickens , horses , cats , snakes ... for the banana flower , mountain , or women showing off the beautiful curves are guides included in the story . Tears flowed down from the highest point of the roof of the cave like fresh drops of holy water .
There are many niches , small compartment in the boat could not hang on to the visitors . There are baffled hit the water obstacle visitors . But this is the ideal home for scientists , researchers and explorers in the value of the population of earth tectonics .
Imprints of earth's history
Before 2010 , the range of unique cave and underground river system has not been mentioned. But the journey to discover the magic of mass of the Earth , a team of scientists from Italy La Venta have found invaluable information about underground rivers and limestone caves have existed for millions of years on earth this . They 've put out 6 reasons to convince the uniqueness of the underground river .
First, here is a rare underground river flows directly into the sea . The tides affect groundwater levels over 5 km , brackish water located in the lower part of the river due to the mix of fresh and salt water .
Second, river systems limestone caves complex . Millions of birds nest and roosting cave with sea creatures in the tidal cave makes life rich tropical cave underground . System creatures , seldom live in deep caves , found in a cave for the biodiversity found here .
Third, underground caves contain large energy resources by geographical location at the equator super warm oceanic climate community , make warm cave environment . Estimated tidal stream suitable for the 150,000 people in the cave every day .
Fourth, the caves contain characteristics of the formation of caves and unique cosmetic science . System of limestone caves above the underground river is an exception in the world . Robertsite new natural mineral found , the promise of finding new mineral belongs to the cave .
Thursday, possesses the river forms the macro , micro special karst and cave formation , helps researchers understand more about Earth's changing .
Friday, fossils of marine mammals Sorenia (now known as sea cows ) , was found in good condition caves . 20 million year old fossil that slips right on cave walls , due to the erosion of limestone in caves .
The information on not only attracts tourists from many countries , but also a valuable gold mine for the study of geology in the world looking to discover .
