Too much sulfur and wind. It was a windy day, like 50 miles/h!
There i snow more the glacier, it melted.
Rocky all the way up to the summit.
Very nice summit with an impressive crater. We went to the higher W summit. Continuous snow cover above 5300m. Road is OK all the way to the trailhead.
Summited with Fabrice. Beautiful surroudings, easy walk to the craters and... a great roasted chicken for dinner in the tent ! If it doesn't snow, you can go there from San Pedro or Calama with a regular car (2 WD).
Went there with Gnome... excellent guide and driver!
Very easy walk, but very rewarding. Great view inside the crater and over Pili and Aguas calientes volcanos.
