Translation of hochmütig

In this email I would like to tell you what occured to me in Italy during the summer vacation last year. So, I went to Italy for four days. First I stayed in Firenze, than I decided to go to Rome.
I even put on my Poncho, a plastic rain coat, in order to protect myself from the aircon-breeze. Somehow I managed to fall asleep and woke up at around six in the morning when we approach Palenque.
It was fantastic to see that each ice berg had its own form and color. Unfortunately we could not reach all galciers, some were blocked by their own ice breaking off and floating in the lake.
