Day 4

Today the tres' plan was to hike up to Camp Canada (Camp 1) and drop a cache of food and gear. They will leave it there and hike back down to base camp. This is what's called the Climb High, Sleep Low philosophy. It helps climbers acclimatize to altitude more efficiently.
I haven't received a SPOT message from them yet, but I expect I will get one soon. I will post back later today.
