Your description is really helpful. Everything you describe seems appealing !
I have a few more questions indeed, if you don't mind :
where is located Menendez exactly compared to Libertador ?
Do you have GPS coordinate (from Google Earth for example) by any chance ?
Is the same access as Libertador (from Las Pailas etc...)
My biggest concern is about the weather. Again I read that is the end of wet season in late February / early March, when we are there. It seems like a beautiful area and we would like to enjoy it as much as possible, which means with as little rain as possible. I Know that you can never predict the weather but :
Do you think it can be a sunny period if even if rains a bit ?or cloudy most of the time ?
Would you say that around the city of Chani it may be less rainy than in Salta, due to higer altitude ?
Regarding the ascent :
How many hours to go from the last camp in the amphitheater to the summit of Libertador ?
On the steep part to reach the NW rim, is the path to follow quite clear ?
Once you reach the NW rim, how many kilometers / hours to reach the actual summit ?
On Google Earth I located the summit on 24°55'51.24"S / 66°23'23.57"W
... do you confirm ?
I have one last question that has not much to do with Chani, but I thought you might help : we intend to go from Salta to San Pedro de Atacama afterwards. I read there are buses through Paso de Jama.
Is it daily or only a couple a week ? Are there less buses in early March ?
A lot of questions, but it is really hard to find information about that area of Argentina... which makes this ascent quite exciting actually !!
Muchas gracias amigo.
