Mountaineering without a guide: English version in progress 49

Hello. If you are English speaking and lost  here by chance, an English version is in progress. At the moment, only the introduction is translated but the rest will come. Sadly, the English language is not my forte. So, please, if you notice my mistakes, thank you for letting me know them.

Click on the picture to go to the tab "Le livre". 
Then, click the English version.
