Jan 4th: 6900 feet and counting!

Today the team reports more climbing but otherwise good travelling conditions. Blue sky, no wind and -20 C. The team covered 24 kilometers in 10 hours of travel. Their current position is S 86.58.093, W85.26.086

They climbed to approximately 6900 feet; they have a little under 2500 feet left to ascend. The South Pole lies at 9300 feet but due to the atmospheric conditions the physiological effect of the altitude is closer to 12,000 feet.

With the increase in altitude the team can expect a small but steady decrease in temperature. In general the temperature decreases approximately 3.5 degrees C with every 1000 feet gained in elevation in a dry climate (it’s less for a a climate with more moisture).
