There was a fascinating BBC produced documentary about that area.
They where on the trail of a late 19th century explorer who had gone into the area to find some "lost city" of some sort, and was never heard from
He got guides from a tribe that had limited contact with the outside that said they could lead him to the city.
Until in the 1930's someone had made contact with this tribe again and they found something that belonged to him.
The tribal elders told this explorer that an old chief had killed the earlier party and eaten them.
In talking with local anthropologists and archeologists, they found out that the villiage they were at was part of the old network of villages that
were connected by trails(roads).
The tribe living there today still lives an a very traditional way.
The grow traditional crops, they also practice aqua-culture, they grow fish in the same man made canals that their ancestors did.
In thier heyday some of the larger towns had populations of up to 10,000 people.
