Waimangu Volcanic Rift Valley

The Waimangu Volcanic Rift Valley is an amazing gem in New Zealand and definitely underappreciated. It’s got a ton of wildlife all in once place.

It is located in the Echo Crater of the Waimangu Volcanic Rift Valley, New Zealand and its acidic water maintains a temperature of about 50–60 °C (122–140 °F). The Inferno Crater lake is also only blue for about 3 days at a time while the water level is high.

From Wikipedia:
The Waimangu Volcanic Rift Valley is the hydrothermal system created on 10 June 1886 by the volcanic eruption of Mount Tarawera, on the North Island of New Zealand. It encompasses Lake Rotomahana, the site of the Pink and White Terraces, as well as the location of the Waimangu Geyser, which was active from 1900 to 1904.[1][2] The area has been increasingly accessible as a tourist attraction and contains Frying Pan Lake, which is the largest hot spring in the world, and the steaming and usually pale blue Inferno Crater Lake, the largest geyser-like feature in the world although the geyser itself cannot be seen since it plays at the bottom of the lake.

Inferno Crater Lake is a large hot spring located in the Waimangu Volcanic Rift Valley on the North Island of New Zealand, and the largest geyser-like feature in the world. The actual geyser is not visible, as it plays underwater at the bottom of the lake, however, fumaroles are visible on the lake’s shore and the rock wall behind it.

The water temperature in the lake ranges from 35 to 80 °C (95 to 176 °F), with acidity up to pH 2.2, and lake levels that vary up to 12 metres (39 ft), following a complicated 38-day cycle that includes an overflow stage. White silica deposits grow up to the overflow level, and the lake’s colour is a result of finely divided silica suspended in the water. At low water levels the lake can be a dull grey colour, changing to an intensely sky blue colour at higher lake levels, in particular after the overflow stage.

Waimangu means ‘black water’ in Maori, the indigenous language of New Zealand. This name comes from the water that was thrown up by the Waimangu Geyser, which was black with mud and rocks.
