The conditions for climbing the Colombian ice sheet are very harsh, with a few indicators that do not meet, and teams already at the door will be banned. Because the appointments are full all day, so when it's your turn, you can only refund your ticket and leave. Our luck was very good. Because of the heavy snow in the morning, all the teams could not go up. The snow stopped at noon. Haha! From the base to the ice sheet, different means of transportation need to be changed to adapt to different terrain. The big wheeled snowmobile that I finally got on could hardly be better! Older people don't need to walk a few steps during the whole journey. It's so exciting that they can experience the ice and snow crystallization for millions of years.
