Getting Used to the Altitude
The team had a great first day skiing Southward. The plan was to make today a half-day and they stuck to the plan, traveling for 3 hours and 45 minutes. During that time, they made 4.5 nautical miles of progress South. The reason for the half-day is acclimatization. It is common to feel the effects of the high altitude (roughly 10k feet or 3050m).
