It took me awhile to see the name 'Nakum' and realize that this is also a place name like Yaxha. I now see a map showing Yaxha, Nakum and Naranjo near Tikal in Guatemala.
I watched the tribal council and it looks as though they are using a pyramid of some kind, as the set for the council, but how much of it is 'beefed up' by the set decorators I can't tell. I kept hoping they'd give a little bit of history of the area; sometimes they have part of a show where you actually get to see more of the location and not so much of the actors.
On a separate note, I've been teased with seeing images of the crocodiles and it looks as though some of those guys may play a role in the show next week. I also hope they'd do some identification of the different reptiles, birds, animals and fish that are around the lake there. Has anyone come across anything like that?
