Big climb today to real mountain altitudes! We left the wooded areas behind and the nature above 4000 meters is very different. Mostly cloudy day today but some nice views of Lhotse and Nuptse peaks. Altitude now is 4400 meters but nobody has difficulties with it. Timo still feels a little week from his sickness and Malla started to feel feverish also. Lets hope it passes as fast as Timo's!
