Unfortunately, after a couple of days into the Abyss of Cenote expedition, the weather took a turn for the worse and trapped the team members inside their tents, where they sheltered from the cold blizzard that battered the thin nylon fabric between a comfortable world curled up inside warm sleeping bags and a world of hurt outside in the maelstrom. Only occasionally did they brave the elements, running across camp to join others cooped inside the communal tent for meals and discussions mostly about the weather. Thankfully, after a day, the clouds cleared and carried with them the snow storm, which revealed a beautiful fresh landscape with a wind swept skittering of snow that covered all tracks up to the entrance of the cave. The teams' agenda inside the Abyss of Cenote cave was back on track, but with less time a new plan had to be followed. An advance team entered the cave and began surveying the upper parts using Leica’s state-of-the-art 3D laser scanner, whilst a second team follow later on to carry out the scientific investigations of the cave.
