A waterfall is a place where water flows over a vertical drop in the course of a stream or river. Waterfalls also occur where meltwater drops over the edge of a tabular iceberg or ice shelf. But, all of the waterfalls don't look exactly like this. There are waterfalls that are so unusual and unique, to provoke disbelief and amazement of visitors. These wonders of nature are very rare and still largely unknown to most people.
# Bigar Cascade Falls, RomaniaThis is the Bigar Cascade Falls situated in Caras-Severin, Romania. It is one of the most beautiful waterfalls in this country, very unique on the way the water is spread and fall, in thiny shred of water. The waterfall is exactly on 45 Paralel which is unique again. The dramatic moss-covered falls are located in the forests of the Anina Mountains and is formed by an underground water spring that spills into the Minis River.
# Eternal Flame Falls, USA
The Eternal Flame Falls is a small waterfall in the Shale Creek Preserve, a section of the Chestnut Ridge Park in New York. Eternal Flame Falls is highly dependant on rainfall and melt water. It is usually only flowing in early spring, or after long bouts of heavy rain. It reaches 30 ft (9 m) high, cascading over sloping shale in two segments. A small grotto, 5 ft (1,5 m) up from the creek bed, to the right houses the natural gas spring that can be ignited to create a flame of 4-8 inches (10-20 cm) in height. When flow is high, the water pours over the grotto, covering the flame and diffusing the light like a lampshade.
# Asik-Asik Falls, PhilippinesLocated in Alamada, North Cotabato the Asik-Asik Spring falls is 60 meters (197 ft) high, and 140 meters (460 ft) wide and the waters of the fall is said to have healing powers. Incidentally, no river or any water body exists above it and the water simply gushes out from rock formations in a cliff at the edge of a hill. A great portion of the cliff is covered with grasses resembling large green curtains.
# Horizontal Falls, AustraliaThe Horizontal Falls or Horizontal Waterfalls (nicknamed the Horries) is the name given to a natural phenomenon on the coast of the Kimberley region in Western Australia. Despite their name, the Horizontal Falls are a fast-moving tidal flow through two narrow, closely aligned gorges of the McLarty Range, located in Talbot Bay. The direction of the flow reverses with each change of tide. As tides in the Kimberley can reach 10 metres (33 ft), a peak tide gives rise to a significant difference in the sea level on either side of each gorge.
# Blood Falls, AntarcticaBlood Falls was discovered in 1911. The Antarctica pioneers first attributed the red color to red algae, but later it was proven to be due only to iron oxides. This chemical compound in the water is a result of metabolism observed in unique microorganisms. Salty water rich in iron leaves a small fissure at the Taylor Glacier. The Blood Waterfall takes its water from a nearby lake covered with a layer of ice which is 400 meters (1,300 ft) deep. Salt content in the water 4 times exceeds the one in the ocean. That's why the water in the fall never freezes even if the temperature is below -10 °C (14 °F).
# Svartifoss, IcelandSvartifoss (Black Fall) is a waterfall in Skaftafell National Park in Iceland, and is one of the most popular sights in the park. It is surrounded by dark lava columns, which gave rise to its name. Other well-known columnar jointing formations are seen at the Giant's Causeway in Northern Ireland, Devil's Tower in Wyoming, USA and on the island of Staffa in Scotland.
