Dallol in 2008
After crossing Lake Asale from Ahmedela we arrive at Dallol.	Hot water is now, contrary to 2002, emerging also in the salt lake; crater of the 1929 phreatic eruption.	Within the crater is now a deeply blue lake covered by thin, floating salt crusts in fast convective motion from right to left.	When a pond dries out strange salt "bushes" rising from the bottom indicate the former water level.
Spectacularly green-coloured ponds below some active salt hornitos.	Sometimes the salt fills cracks in the ground, creating green terraces "in suspension".	Dario Tedesco from Napoli University taking gas samples.	Minute orange mineral terraces seem like lace draped near this pond.
An active hornito ejects water with plenty of minerals which form deposits mimicking a head covered by grey hair.	Dozens of hornitos are active within a small area, together creating a symphony of whistles and puffing.	Close-up of an egg-shaped salt deposit, caused by sublimation around a micro-fumarole.	Sublimation from fumaroles causes salt to deposit in some strange shapes like branches in the wind.
