Hi. Its been so long. I cannot be sure. I do remember it being similar to Aconcagua.
The old mining Camp 9,000 ft. Base camp at the end of the mining road 12,500 or 13,000 feet. Next camp 15,000. High camp arond the corner from where all the stones are (old camps) around 19,000 ft. Where we camped was near the old grave on the windswept side of the mountain. Not too much protection here from the elements.
I am not sure the road to mining camp has reopened since the mud and rock slide of 2 years ago. You may have to detour to the South Face.
Hope this helps a bit. I will ask my sources.
