Alan will not arrive in BC for a few more days yet, as he and his IMG guides are now in Mendoza awaiting the rest of the team and preparing the last of their gear before purchasing their climbing permits for the mountain. Expect good updates at every step of the process, as Alan always does an excellent job of keeping us informed of his progress and giving great insights into what it is like to climb the mountain he is currently on. I expect no less this time, especially considering that he has already successfully climbed Aconcagua in the past.
An example of Alan's great work is the video below, during which he talks about his prep work for the mountain and shows off the gear he's using on this climb. He doesn't just show us the individual pieces however, as he actually shows us each piece in regards to where it is used during the climb. It is very insightful for those that wonder where all that gear is put to use.
