It is a series of strong events that we are experiencing during the third season. After the sonar survey, Dan Blankenship's long-held belief that there is more information about the room, which is 235 feet up to 10-X, has more room. It is a room with wooden columns, side tunnels, a box and even human remains. On the other hand, Rick and Marty Lagina start with their partners in removing the obstacle columns to allow the divers to do the job.
