Description
El Tatio is the world’s highest geyser field at 4,320 metres above sea level in the northern Chilean Atacama — its proximity to the Bolivian border and location in the driest non-polar desert on Earth creates unique visual conditions. The geyser field is most active at dawn when the temperature differential between the superheated water (85°C at altitude) and the ambient air (minus 10°C at sunrise) produces the maximum steam column height and density. Arriving before sunrise — a logistically demanding 4am departure from San Pedro de Atacama — enables photography during the golden hour when dozens of simultaneous steam columns are backlit by the rising sun, each column casting a long shadow across the sinter flat. The steam freezes into ice crystals around each vent within a metre of the ground. Shot on a 24-70mm at f/11, the foreground vent ice crystals are sharp while the background column forest extends to the volcanic peaks of the Bolivian altiplano.
