As he enjoys the beautiful scenery on his hike towards Glacier de Tete Rousse, he also notices that clouds are dispersing from the sky, which gives him a reason to suspect that the barometric pressure has changed.
After arriving at Refuge l'Aig du Gouter, Mike sets the Baro mode on so that the barometric pressure changes do not affect the altitude readings anymore.
Before hitting the sack, Mike plans out the next day's activities. He needs to get up early because he has a long way to travel. So, first he checks the time of sunrise with Start/Data in the Alarm menu and then sets an alarm to wake him up just before dawn. He also compares the altitude reading to the one on the map to see that they match. Then he leaves Suunto X9 to charge its battery.
