Unforeseen Twist
After spending around a week on the water, Karl, the geologist and now the group leader informed the rest that they were quickly approaching towards the San Pedro Canyon which is a dangerous river line full of waterfalls and stones and rapid stretches, surely, not good at all for a hand-made boat. Karl said that he has a map but no one could not understand why he even made the boat head in the wrong direction and what came to their surprise was that their leader denied going ahead.
