Frying Pan Lake is the largest
hot spring in the world, located in the Echo Crater of the Waimangu Volcanic
Rift Valley New Zealand. In 1886, the most destructive volcanic eruption of
Mount Tarawera results in formation of Echo Crater and nearly killed more than
one hundred people. The crater’s partly filled with rainwater and heated
groundwater, and its acidic water maintains a temperature of about 50–60 °C. Frying
Pan Lake is also called Waimangu Cauldron till 1960’s, however not widely used.
In 1917, another massive eruption in Echo Crater resulting bigger part of hot
springs to reach its current size. The Frying Pan Lake water is naturally
steaming and can appear to be boiling due to carbon dioxide and hydrogen
sulphide gas bubbling to the surface, however, the lake's average temperature
is 55 °C. The Frying Pan Lake is recognized to be as the youngest geothermal
system in the world, as it occupies 38,000 square meters as a part of a
volcanic crater with a flat floor that is six meters deep and vents that could
go deep up to 20 meters.
The last eruption in Echo Crater
taken place in 1973, which is badly, damaged the Trinity Terrace area, which
was extremely colorful sinter terrace. However, these terraces are still
visible on the western shore of Lake. The lake and its outflow, have an average
pH level of 3.8, although some of the boiling hot springs and vents on the
lake's bed feed it with alkaline water of pH 8.2 to 8.7. Monolithic Cathedral
Rocks are bounded on the north side of Lake, made of rhyolitic lava at least
60,000 years old. The massive eruption of 1917 has completely changed the shape
of Echo Crater, also disappeared fumarole known Devil’s Blowhole in that event.
In Photos, the steam looks like low hanging fog in the early morning hours of
autumn day. The Frying Pan Lake has special flair, showing the appearance of a
large boiling cauldron.
The various gradients of blue,
green algae Mastigocladus Laminosus, eukaryotic algae Cyanidium Caldarium are
present in the lake. The site of the extinct Waimangu Geyser is located not far
from its north-eastern shore. Besides the steam and gases coming off, you will
also easily notice the natural chimney at the side of the lake. The outflow
water volume is Frying Pan Lake has varied. The unique cyclic nature of the
hydrothermal system interconnecting Frying Pan Lake and the adjacent Inferno
Crater Lake water levels and overflow volumes follow a complicated rhythm that
repeats itself roughly every 38 days. When the water level and temperature of
Inferno Crater Lake increase, the water level and outflow of Frying Pan Lake drop.
Frying Pan Lake is one of the first major attractions encountered along the
wheelchair-friendly main Waimangu walking track. Frying Pan Lake is a fantastic
spot in Waimangu, where you can enjoy self-guided nature walks, amazing
landscape, geysers, lakes, volcanic craters, bird life, plants and breathtaking
adventure.
