Jomblang Cave or Luweng Jomblang is a 50-meter vertical collapse doline type cave in Gunung Kidul Regency, Yogyakarta Province, Indonesia. This cave was formed due to geological processes in which soil and vegetation on the surface collapsed to the bottom of the earth into a sinkhole thousands of years ago into ancient forests in the cave.
Inside the cave grows endemic vegetation and a place for conservation of ancient plants. Sunlight bursts into 90 meters of Luweng Grubug to form a light pole, illuminating the beautiful flowstone and water dripping from a height in a dark room.
Characteristics
Jomblang Cave is one of the caves of hundreds of caves in the Gunung Sewu Geopark. This doline collapse cave is formed due to the surface process collapsing and forming a sinkhole. Ancient plants that lived on the surface also fell to the bottom of the earth, adapted and continued to grow until now as a very rare endemic plant.
This cave has a mouth hole 50 meters wide and 60 meters deep. On the surface of the earth, as far as the eye can see in the form of karst hills and teak trees, but inside Jomblang Cave lies a view of fertile forest. Moss, ferns, bushes, and large trees grow tightly as a conservation area where vegetation species are not found elsewhere.
Goa Jomblang has alleys formed by underground streams with various beautiful ornaments. The walls of the cave aisle such as beautiful crystal stones, stalactites and stalagmites are accompanied by the roar of the river and a bright light in the dark.
Grubug Cave and the light of heaven
One of the aisles in Goa Jomblang has a length of 300 meters and connects to Grubug Cave or Luweng Grubuk which has a giant chamber. A ray of sunlight bursts into the cave at a depth of 90 meters and forms a pillar of light and illuminates the beautiful flowstone.
