Biologists Jimmy, Grimaldo, and Alejandra are excited about the water pools and rich fauna and flora at north-east part of the crater and they ask Gunther, Aaron and Rafael to take them into this area. The biologists stay behind by the crocodile pool while the magnetometer team opened the trail all the way to the NE rim of the crater. They followed the dry river channel and continued collecting magnetic data while observing crocodiles, spider monkeys, numerous spiders and unusual insects. An unusual bird with a 2m wing span and a horn on its head was observed by the magnetometer team. A picture of this bird excites the group’s ornithologist (Oswaldo). Jim,Vicki, Tim and Holly travelling by boat and foot, sampled soil and soil nodules at the confluence of the Arroyo stream and Rio Manupare.
