Do you have any idea what is that in picture , bright and dark.
Lake Kelimutu or ‘the three colored lake’ is three crater lakes of mount Kelimutu located on Flores Island, East Nusa Tenggara, Indonesia. The three crater lakes are a haunting and possibly haunted sight.
Considered to be the resting place for departed souls, the lakes are locally referred to as “the lake of old people,” “the lake of young men and maidens,” and “the lake of evil spirits.” Bizarrely, all three lakes change color dramatically and unpredictably, from blue or green to black or red. Reaching the popular sight requires a long drive on a steep and winding road.
The lakes have been a source of minorphreatic eruptions in historical time. Thesummit of the compound 1639-m-high Kelimutu volcano is elongated two km in a WNW-ESE direction; the older cones of Kelido and Kelibara are located respectively three km to the north and two km to the south. The scenic lakes are a popular tourist destination.
Kelimutu is also of interest to geologists because the three lakes are different colors yet are at the crest of the same volcano. According to the local officer at Kelimutu National Park, the colour changes as a result of chemical reactions resulting from the minerals contained in the lake perhaps triggered by volcano gas activity.
