Having visited the Waiotapu Thermal Wonderland a number of times I knew what to expect. Lady Knox Geyser erupts to heights up to 20 metres. Its induced by dropping a surfactant into the vent each day at 10:15am. This draws dozens to hundreds of tourists each day. Having photographed this geyser before, I focused on watching the people. Compared to a 2013 when I first visited, the amount of mobile phones that were held up was eye opening. Almost every other person held up their phones for a photo or video.
