Rotorua, New Zealand - 1 March 2019; Rotorua in New Zealand's North Island is an extended area packed with geothermal vents, boiling mud springs, sulphur fields, steaming fissures and geysers. It has an immense primeval beauty and drama, combined with a feeling of utter manifest chaos - at any moment, you half expect a dinosaur to emerge from the steaming, sulfurous mists. Oh, did I forget to mention? - and it all reeks a bit! Here we see the spectacular Pohutu Geyser.
