We did the 10km walk uphill towards Interim camp. (The jump between Base Camp 5150m (BC) and Advanced Base Camp 6400m (ABC) is too big to do in one hit, so we have to stop at Interim.
Along the way I caught up with another group (7 summits club) Their guide (Noel) was the only one who spoke English, he was from Ireland. A good bloke, next year he is going for 4x 8000m peaks in 4 weeks.. a massive effort and has never been done before. Good luck with the weather on that one Noel!
There isn’t much to say about interim apart from you really want to spend as least time as possible there.
The only water source comes from a frozen lake, above that lake is where all the yaks are held as they walk from BC to ABC, so they are excreting in the water, people also use the protected part as their toilet as well. Therefore sickness at Interim is rife!
Phil, who owns and runs adventure club, quarantined his clients for 16 hours in their tents whilst at interim. They were brought food, to their tents and weren’t allowed to leave until the following day when they made their way to ABC. He said that even the air there will make them sick!
Jamie on the other hand had plan! The only problem was convincing the yak drivers to take our load over the next valley were it is much cleaner. They agreed so we stayed in a pristine little valley right next to some 40m ice pinnacles that were creaking and cracking all night and day, good call Jamie!
We stayed at Interim for 2 nights, none of us got sick.
