Published by the Bohol ChronicleThere is a rare geological formation in Bohol - said to be the only one in the country but not part of the mystifying Chocolate Hills - which could be one of only two or few of their kind on the planet: The Ilihan hill.
Located in Tubigon town, Ilihan hill is monstrously huge "solid molten lava" believed to be thrown from the mouth of a now sunken dead volcano some 30 million years ago, according to Mayor Luna Piezas quoting the "finding" of a group from stands for the United Nations Educational, Scientific and Cultural Organization (UNESCO).
The world - or planet Earth - is about 4.5 billion years old.
The volcano must have been sunken somewhere between Bohol and Cebu, the mayor said, or Bohol and Leyte.The experts, accompanied by a UNESCO staff from Tubigon, recently visited the mayor at his office and conveyed to him their discovery.
Piezas said in a Chronicle exclusive that the group told him the geological formation and evolution of the Ilihan hill is entirely different from those of the world-renowned Chocolate Hills in Carmen.
UNESCO just organized a global search for "New Seven Wonders of Nature" ranking the Chocolate Hills among the top 77 nominees.
Piezas said the UNESCO group that surprised him with the rarity of the hill in his town just conducted a technical visit to the Chocolate Hills before they intentionally went to Ilihan.
The group told the mayor that Ilihan hill is a plug, a massive cylindrical formation of solidified lava that once blocked the vent of a volcano. It is also technically called a volcanic neck.
The hill has since been covered with trees and other vegetations, and even inhabited by "tribe-like" people often described as a "cult" for their ways and norms as haunting as the supposed origin of their hill dwelling.
UNESCO experts told the mayor that the only other known plug similar to that in Tubigon is found in Brazil.
The hill totally formed by solidified molten lava rises in this place on earth where no volcano has ever existed - not even an extinct one has ever been known.
Ilihan's volcanic rock appearance will be most emphasized once the hill is totally stripped of its foliage or vegetation, the mayor was further told.
In a national park and preserve in Alaska is found the Valley of Ten Thousand Smokes which entrance is guarded by two solidified lava formations, but which look rocky and not green.
The Tubigon mayor wished to know more if Ilihan evolution as sluggish, thicker lava moving slowly to the surface of a mid-ocean shield volcano after less-violent blasts.
