Ngakoro järv

Maaliline Ngakoro ehk Vanaisa järv Waiotapu geotermaalalal, Uus-Meremaal. Järve toitvate allikate keskmine temperatuur jääb 75-90 kraadi Celsiuse vahele, kuid kuna järve pindala on suur, siis ülemistes kihtides on vesi ainult õrnalt leige. Ngakoro tekkis üle 700 aasta tagasi termaalpurske tagajärjel ning see vanus on ka ilmselt sellise nime saamise peamine põhjus.

Scenic Lake Ngakoro (grandfather in maori) in Waiotapu geothermal area, New Zealand. The springs feeding the lake have an average temperature of 75-90 degrees Celsius but as the surface area of the lake is quite large, the water is only mildly warm in upper parts. Ngakoro was formed after an eruption more than 700 years ago and the age is probably the main reason behind its name.
