Luis leaves behind geocaches for other time travelers. He doesn't however, know that he made them out of a toxic material. The crew must find one in all the environments of 100 million AD in 80 minutes.
This is one of a few episodes where CG scolds a crew mate,in this case:Luis for he left behind geocaches, which violates one of the mission directives.
