Enormous Fish Trap                   Miles of Earthworks Harvested Seafood
from Amazon Floods  By Michael Stowe</A>

Deep in the Amazon jungles of Bolivia, researchers are uncovering the remains
of an incredibly advanced network of earthworks and ponds that was created
more than 300 years ago. The long, curving earthen structures were built as
permanent fish traps to take advantage of seasonal flooding, when fish
migrated to spawn in the flooded savannas, says Clark Erickson, Associate
Curator of the American Section at the University of Pennsylvania Museum of
Archaeology and Anthropology
