Danau Warna Nan Mempesona

Banyak danau nan memukau di seluruh dunia yg menawarkan warna airnya berbeda dengan warna air yang biasa kita jumpai sehari hari. Inilah beberapa diantaranya...


 Laguna Verde
The Laguna Verde, a salt water lake, is located in the southwest of the high plains of Bolivia. For those of you who speak Spanish, it will be no surprise to you that the waters of the Laguna Verde (Green Lagoon) are an amazing shade of green. Situated at the foot of the Licancabur Volcano, the beautiful green hue is caused by debris that includes copper deposits. The colored lake is also known for its beautiful surroundings and hot springs.




Band-e Amir 
Band-e Amir is a chain of 6 deep blue lakes located high in the Hindu Kush Mountains of Central Afghanistan. They became Afghanistan’s first national park in 2008. The beautiful lakes were formed from mineral rich water that seeped out of faults and cracks in the rocky landscape. The high mineral content of the lakes are also the cause for the intense and varying colors of the lake waters.




Lake Pukaki
Lake Pukaki in New Zealand gives the color “glacier blue” a whole new meaning. The colorful lake was created by receding glaciers decades ago. Today, that glacier feed produces finely ground rock particles, known as glacier flour, that give the lake a distinct icy blue color. Lake Pukaki is the second largest alpine lake in the Mackenzie Basin, located in New Zealand’s South Island.




Laguna Colorada
 
The Laguna Colorada is located in Bolivia close to the border of Chili. The reddish color of the waters is thanks to red sediments and the pigmentation of algae. Other than the red waters, the Laguna Colorada is also home to many varieties of flamingos and a number of white borax islands. Borax islands are formed by the repeated evaporation of seasonal lakes, like the Laguna Colorada.




Kelimutu 
The Kelimutu Volcano contains three summit crater lakes of different colors. Tiwu Ata Mbupu is usually blue; Tiwu Nuwa Muri Koo Fai is normally green; and Tiwu Ata Polo is usually a reddish hue. The source of the unique color combination is thought to be openings in the earth’s crust, known as fumaroles. The beautiful lakes are a popular tourist attraction, and also attract many geologists on a yearly basis. The fact that the three lakes are all different colors, yet are located on the same volcano crest, is a source of much debate and interest.




Havasu Falls
The Havasu Canyon is part of the Grand Canyon and is inhabited by the Havasupai tribe, who live in the small town of Supai. It is one of the most remote villages in America and normal access is via a helicopter ride or a 13 km (8 mile) dusty horse trail from a car park at Hualapai Hilltop.

The main reason to visit the Havasupai (which means “people of the blue-green water”) is because of the colorful waters and falls. The most spectacular of these is Havasu Falls. The beautiful color of the water is caused by carbonate minerals settling to the bottom, turning it white, and acting as a reflector of the surrounding green and brown mossy cliffs plus the blue sky.




Moraine Lake
Fed by glaciers, Moraine Lake, locate in Banff National Park, is known for its stunning blue waters. The coloration is thanks to light refracting off the glacier flour. Located in the Valley of the Ten Peaks, Moraine Lake is surrounded by the beauty of the impressive Canadian Rocky Mountains. There are a number of hiking trails around Moraine Lake. Just be sure to check the trail conditions before you set out to go as they are sometimes restricted because of grizzly bear activity.




Lake Nakuru 
Lake Nakuru is a very shallow lake in central Kenya. The lake’s abundance of algae attracts vast quantities of lesser flamingos, sometimes more than one million at once. Often called the greatest bird spectacle on earth, the flamingos literally turn the shores pink. Sadly, in recent years the number of flamingos has been decreasing, due to environmental degradation and pollution.




Jiuzhaigou
The Jiuzhaigou Valley of China is home to dozens of blue, green and turquoise-colored lakes. The local people call these bodies of water “Haizi,” which in Chinese means “son of the sea.” The numerous colorful lakes were created by glacier activity, and today, many waterfalls empty into these pristine waters. The beautifully colored water is also known to be extremely clear, in many cases visitors are able to see to the bottom of the lakes.




Plitvice Lakes
 
Located in a national park in Croatia, the Plitvice Lakes are sixteen lakes that are located near the border of Bosnia and Herzegovina. The beautiful lakes are famous for their unique colors, including azure, green, blue, and gray. The lakes’ colorations changes consistently, depending on the quantity of minerals, deposits, or organism in each body, or how the sun is hitting the water.




Peyto lake
Peyto Lake (pea-toe) is a glacier-fed lake located in Banff National Park in the Canadian Rockies. The lake itself is easily accessed from the Icefields Parkway.

It was named for Bill Peyto, an early trail guide and trapper in the Banff area.

The lake is formed in a valley of the Waputik Range, between Caldron Peak, Peyto Peak and Mount Jimmy Simpson, at an elevation of 1,860 m (6,100 ft).

During the summer, significant amounts of glacial rock flour flow into the lake, and these suspended rock particles give the lake a bright, turquoise color. Because of its bright color, photos of the lake often appear in illustrated books, and area around the lake is a popular sightseeing spot for tourists in the park. The lake is best seen from Bow Summit, the highest point on the Icefield Parkway.

The lake is fed by the Peyto Creek, which drains water from the Caldron Lake and Peyto Glacier (part of the Wapta Icefield), and flows into the Mistaya River.




Ijen lake
The Ijen volcano complex is a group of stratovolcanoes, in East Java, Indonesia. It is inside a larger caldera Ijen, which is about 20 kilometers wide. The Gunung Merapi stratovolcano is the highest point of that complex. The name of this volcano resembles that of a different volcano, Mount Merapi in central Java, also known as Gunung Merapi. The name "Merapi" means "fire" in the Indonesian language.

West of Gunung Merapi is the Ijen volcano, which has a one-kilometer-wide turquoise-colored acid crater lake. The lake is the site of a labor-intensive sulfur mining operation, in which sulfur-laden baskets are carried by hand from the crater floor. Many other post-caldera cones and craters are located within the caldera or along its rim. The largest concentration of post-caldera cones forms an east/west-trending zone across the southern side of the caldera. The active crater at Kawah Ijen has an equivalent radius of 361 metres (1,184 ft), a surface of 41 square kilometres (16 sq mi). It is 200 metres (660 ft) deep and has a volume of 36 cubic hectometres (29,000 acre·ft).

In 2008, explorer George Kourounis took a small rubber boat out onto the acid lake to measure its acidity. The pH of the water in the crater was measured to be 0.5 due to sulfuric acid.
