"Though possessing numerous geysers, none erupt very high. The highest eruption observed has been around six meters in height. The average geyser eruption height at El Tatio is about 75 centimeters" (Glennon, J.A. and Pfaff. R.M., 2003). The best time to see them is at sunrise when each geyser is surmounted by a column of steam that condenses in the bitterly cold morning air. The steam plumes disappear as the air warms up. It is also possible to bathe in the hot geyser water in a small pool. However parts of the field are very dangerous with a thin crust over almost boiling mud so ask your guide where you may go.
There is wreckage at the site from an old project for harnessing geothermal power. The idea has recently been revived by the Chilean government and is meeting with heavy public resistance due to the touristic value the geyser field represents.
"El Tatio" roughly translates to "the grandfather"." (Glennon, J.A. and Pfaff, R.M., 2003).
2009 prospection controversy
In mid-September 2009, a 200-foot permanent steam column was noticed. Further developments point to damage done by prospection by GDN, a geothermal exploitation company jointly owned by Chilean State holdings and an Italian Energy consortium. News clipping
