[Aztlan] Tsunami Wipes Out Olmec

[Robert Kirsch II]

I imagine the Isthmus of Tehuantepec would have had its
share of bad weather and storm surges. Is there any evidence for
a tsunamis wave rising up across the Isthmus, burying everything?
Were the lowlands flooded with salt water? Where would  you dig to find remnants of a flood?
     The Olmecs built canals to carry the heads. Of course the rafts would bottom out in a swamp, they would have to dig ahead of it, creating-inadvertantly-a canal. Only other options-fly them with sails and ropes and roll them on a cart with wheels. As for rafts, what shapes are most bouyant with the least surface area-like a canoe-the point of depth is in the center, the canoe would have to be balanced on both sides. The wood used to float them, unknown, but Balsa wood happens to have grown in the region, what phytolith evidence exists for the varieties of trees that forested the region in 3750 B.P. 
They used ropes to move the stone, we know this from the Olmec altar/thrones. I have found some evidence for the canals. If I am not mistaken, the clays found layered with travertine came from collection over a large area of excavation. 
    Lake Catemaco is quite formidable, its waterways and river must have been the prize of the Olmec. What findings have been made at Catemaco, any ideas. Perhaps the lake holds its secrets in the depths and a search might find stone effigies, celts or jade figurines. Such a large body of water must have had some significance for the Olmec, aquatic resources aside.                                      Robert Kirsch
